FX364B Single-Ended TDR/S&H
The FX364B is an instrumentation Analog Front End (AFE) integrated circuit for time-domain reflectometry step stimulus and sampling of single-ended transmission sub-systems. It integrates two high-speed functional blocks: i) a controlled-amplitude single-ended voltage step generator - a Time Domain Reflectometer (TDR) step-stimulus, and; ii) a differential, dual-rank, sample-and-hold - to digitize the reflected voltage waveform that indicates an impedance discontinuity. With the step-generator disabled, the sample and hold amplifier (S&HA) acts as a single Ended Digital Sampling Oscilloscope (DSO) AFE, facilitating sampling of 28G NRZ or PAM4 sample-rate eyes.
The FX364B is architecture/pin/function similar to the FX362B (a full-differential TDR + S&HA), with 2 exceptions: i) only aioP is driven (both aioP/aioN are terminated); ii) the FX364B peak step-stimulus is half that of FX362B.
