Teledyne LeCroy announces M-PHY receiver test solution for PeRT3 Phoenix

MIPI Alliance Members Meeting, CHICAGO, USA: Teledyne LeCroy, the worldwide leader in high speed I/O analysis and protocol test solutions, announced its new MIPI M-PHY Receiver Test solution for the PeRT3 Phoenix - Protocol Enabled Receiver and Transmitter Tolerance Tester.

The M-PHY Receiver Test option adds support for M-PHY to the industry's only protocol enabled receiver and transmitter tolerance tester. M-PHY technology is targeted at mobile devices such as tablets, smart phones and thin laptops. Forecast projections indicate that the quantity of PCs sold will decline as these smaller M-PHY based mobile products grow in volume.

The Teledyne LeCroy M-PHY Receiver Test solution's support for HS GEAR1, GEAR2 and GEAR3 and PWM Mode (G0-G7) gives designers the flexibility to perform tests at the full range of data rates for comprehensive insights into their designs.

The auto calibration support for high speed GEARs reduces the complexity of setup, saves time, and enables users to test devices faster. Margin testing for high speed gears allows designers to validate and stress their devices to maximum potential resulting in competitive technical specifications for their products.

The PeRT3 contains user customizable state-machines to model real serial data protocols. Customizability allows the user to test a device beyond normal expected behavior and also to isolate device specific issues. Because the PeRT3 internally handles the physical layer functions (such as coding/decoding, scrambling/descrambling, packet field detection, etc.), the user can focus at the state level on isolating difficult bugs such as those that cross between protocol and signal integrity.

The user can modify the state-machine to help isolate protocol issues. The user can set points within the state-machine to trigger external equipment. A common usage is to trigger an oscilloscope at a specific point within the negotiation to observe the signal quality or message content.
