Eclipse X34 MIPI M-PHY Protocol Analyzer

The Teledyne LeCroy Eclipse MIPI M-PHY protocol analyzer is for customers developing M-PHY GEAR 1/2/3 at up to x4 lane width. Supporting UniPro/UFS as well as M-PCIe and SSIC, this protocol analyzer is the most versatile M-Phy analyzer on the market. The Eclipse X34 also boasts the fastest lock time at Gear2 and 3, the deepest recording memory and the smallest footprint. Using either SMA or solder down probing gives UniPro/UFS designers flexibility to capture and record M-PHY bus traffic.

Eclipse M32 UniPro/UFS Analyzer/Exerciser   The Eclipse M32 analyzes bi-directional UniPro and UFS traffic, performing protocol sequence and timing analysis and packet header and payload inspection, to provide complete protocol debug and analysis of UniPro and UFS devices. Trace Validation uses state machine logic to analyze captured traces algorithmically without user intervention. The Eclipse M32 also provides conformance/compliance verification, as well as margin, corner case, and automated stress testing.

MIPI® M-PHY is a serial interface technology with high bandwidth capabilities, which is particularly developed for mobile applications to obtain low pin count combined with very good power efficiency. It is targeted to be suitable for multiple protocols and for a wide range of applications.

M-PHY uses lanes for communication. Each lane is a differential pair. M-PHY supports multiple lanes and lanes can be asynchronous.

M-PHY defines both low speed and high speed data rates. Within both low speed and high speed, multiple gears are defined. Low speed uses a Pulse Width Modulation and Gears 1-7 support a range of speeds from 3Mbps up to 576 Mbps. High Speed uses NRZ signaling and supports speeds of .998Gbps up to 11.66Gbps via Gears 1-4. Information transmitted on the lanes uses 8b/10b encoding.

UniPro is a MIPI defined transport specification. Uniport-M is the UniPro transport over M-PHY. UniPro enables upper layer applications to move data over the M-PHY bus although it is Phy layer agnostic. UniPro is applicable to a wide range of Device types such as modems, storage subsystems, Non-volatile memory, displays, and camera sensors. It is also applicable to different types of data traffic such as control messages, bulk data transfer and packetized streaming. A full Layer 1.5-4 specification, UniPro defines packets and frames for moving information across a network from device to device. It also defines the structures and mechanisms for connection management, power and state management, flow control and error handling.

JEDEC defines the Universal Flash Storage (UFS) specification. UFS is a simple, high performance, mass storage device with a serial interface. It is primarily for use in mobile systems, between host processing and mass storage memory devices. The UFS electrical interface is based on the MIPI M-PHY specification which together with the MIPI UniPro specification forms the interconnect of the UFS interface. UFS is based on the SCSI Architectural Model (SAM). The UFS command set is based on the SCSI Primary Command (SPC) and SCSI Block Command (SBC) sets.

Protocol Analysis and Traffic Generation

Teledyne LeCroy offers both protocol analyzers and traffic generators or exercisers to address the M-PHY market. Our protocol analyzers offer unique and configurable views that allow users the ability easily visualize the M-PHY traffic. From the low level M-PHY primitives up through the UFS SCSI command sets we show activity on the bus as a complete picture of all events, and allow views to the lowest level bytes or to the highest level command transactions. Our exerciser and expert system analysis run conformance and stress test cases, then verify that the resulting protocol sequences and packets conform to the CTS. Extensive reporting and analysis tools include reports by test parameters – status, individual tests, or test rules, and within tests by packet characteristics such as packet number, byte, speed, link, etc. Summary and full reports and pass/fail reports are also provided.

As a contributing member of both MIPI and JEDEC, Teledyne LeCroy stays informed and up to date on the latest specifications and continues to update the roadmap for their M-PHY and UniPro/UFS tools.

The Eclipse X34 can monitor, capture, decode and analyze multiple transmission modes with different bit-signaling, clocking schemes and rates that support bandwidth ranges (M-PHY Gears 1 to 3). Two independent reference clocks, Rate A and B operate at 19.2 and 26 MHz with 8B/10B, encoding can be tracked and displayed. PMW Modes G0 to G5 are supported and displayed in the trace view. The application display is highly configurable and can be modified to most users debugging styles. A customizable multi-state trigger makes it easy to discover protocol issues on the bus. Features such as multiple local, global timers and counters allow the user advanced control to create sophisticated trigger sequences. The Eclipse can time correlate its traces to other Teledyne LeCroy supported protocols and buses. This multi-protocol support will make it useful to help debug DDR memory and other serial protocols on low power devices.

The Eclipse X34 features up to 4 lanes of traffic capture and up to 32 GB trace depth. Teledyne LeCroy also provides a variety of probing connectivity options, including SMA, multi-lead solder-down tapping and a special Mid-bus probe designed for M-PHY. The M-PHY Mid-bus probe has been defined by Teledyne LeCroy and will build on the existing footprint for PCI Express giving developers another method to get probing access to M-PHY signals.

The Eclipse x34 can be connected to the host by either USB 2.0/3.0 or Ethernet 10/100/1000 LAN as standard features. By connecting over a LAN, engineers can operate the system remotely (e.g., control an analyzer operating in a remote lab). Also, engineers working collaboratively can time-share use of a single analyzer, reducing the need for multiple systems, and increasing the cost effectiveness of the product.

The Eclipse X34 is licensable to accommodate different lane, memory and gear configurations to match user requirements with available budgets.

MIPI M-PHY SMA Probe

The Teledyne LeCroy M-PHY x4 SMA Probe allows developers using an embedded M-PHY bus in their PCB designs to quickly tap into the signal traces through SMA connectors and capture bus traffic for protocol analysis and debugging.

The probe features SMA connectors for each of the 16 differential transmit/receiver pairs that support up to a x4 link or 4 differential pairs per x1 link. Each SMA connection uses termination as defined by the specification to minimize signal degradation of the M-PHY bus signals, while providing reliable capture of all M-PHY traffic.

The probe will connect to a Teledyne LeCroy M-PHY Protocol Analyzer via an iPass straight cable, and supports M-PHY data rates including GEAR1, GEAR2, GEAR3 at link widths from x1 to x4.

Eclipse X34 Multi-lead Probe Datasheet
The Teledyne LeCroy M-PHY Multi-lead Probe allows developers using an embedded  M-PHY bus in their PCB designs to tap into the signal traces directly and capture bus traffic for protocol analysis and debugging.
 
The probe allows for individual connection to each separate transmit-pair and receive-pair of each serial lane, allowing flexibility to connect to any accessible points on the surface of the PCB.  Each connection uses a high-impedance electrical probe to minimize perturbation of the M-PHY bus signals, while providing reliable capture of all M-PHY traffic.
 
The probe will connect to a Teledyne LeCroy Eclipse X34 M-PHY Protocol Analyzer via a Multi-lead Probe Pod.  Support is provided for M-PHY data rates of GEAR1, GEAR2 and GEAR3, and at lane widths from x1 to x4.  Each individual lane connection is made by using  two 294 mm (11.6”) extender coax cables connecting into 71 mm (2.8”) flextip connectors which each are attached to an individual transmit-pair or receive-pair on the surface of the PCB.
