The ADC342x are a high-linearity, ultra-low power, quad-channel, 12-bit, 25-MSPS to 125-MSPS, analog-to-digital converter (ADC) family. The devices are designed specifically to support demanding, high input frequency signals with large dynamic range requirements. An input clock divider allows more flexibility for system clock architecture design and the SYSREF input enables complete system synchronization. The ADC342x family supports serial low-voltage differential signaling (LVDS) in order to reduce the number of interface lines, thus allowing for high system integration density. The serial LVDS interface is two-wire, where each ADC data are serialized and output over two LVDS pairs. An internal phase-locked loop (PLL) multiplies the incoming ADC sampling clock to derive the bit clock that is used to serialize the 12-bit output data from each channel. In addition to the serial data streams, the frame and bit clocks are also transmitted as LVDS outputs.

TIDA-00499 — Diseño de referencia de registrador de fallas digital y transitorio AFE mediante el uso de amplifica

While Digital Fault Recorders (DFRs) can detect transients in 17/20 μs at 60/50 Hz, transient recorders capture disturbances that can peak and decay well within a microsecond. This reference design demonstrates the capturing of transient inputs at up to 1 MHz for DFR and 25 MHz for (...)
