Receiver test for MIPI D-PHY v2.0, uses Tek’s AWGs
MIPI designers, Tek says, who are working on autonomous driving systems or in-vehicle infotainment, gain simplified PHY receiver test set up and faster test execution combined with signal fidelity and flexible support for in-depth debug and margin testing. This solution expands Tektronix’ extensive portfolio of MIPI PHY transmitter and receiver and protocol test solutions for its industry leading real-time oscilloscopes, arbitrary waveform generators and BERTScope bit error rate testers.
Tek sees the latest high-speed MIPI standards gaining broad adoption in the automotive sector for applications ranging from self-driving cars to vehicle telematics. Receiver testing has emerged as one of the more difficult challenges due to increased complexity, higher speeds, different data rates and modes (HS, LP, HS-LP) and backward compatibility requirements.
The latest Tektronix MIPI receiver test solutions consist of DPHYXpress and CPHXpress software packages running on AWG70000 Series arbitrary waveform generators (pictured, above). These solutions offer signal fidelity with up to 50 Gsample/sec sampling rate and 10-bit vertical resolution. The software gives users full control to change receiver test parameters such as rise time, amplitude, jitter, setup/hold time for CLK, skew, noise, duty cycle distortion and more. It also allows users to de-embed cable effects using a direct synthesis method. To reduce test times, the applications offer a batch mode for receiver margin testing to easily create and replay libraries of complied stress waveforms with different jitter and noise parameters.
The DPHYXpress and CPHYXpress solutions are available for download now from the Tektronix website. Pricing is $10,000 (US).
