AD9973BBCZRL

Overview

The AD9973BBCZRL is a dual-channel CCD signal processor featuring a Precision Timing core with 240 ps resolution at 65 MHz. It integrates two analog front ends, each containing a correlated double sampler (CDS), a black level clamp, and a variable gain amplifier (VGA) providing 6 dB to 42 dB gain. Each channel includes a 14-bit, 65 MSPS analog-to-digital converter (ADC). The device operates on a 1.8 V analog and digital core supply voltage and utilizes a reduced range LVDS interface for data outputs. It is housed in a 6 mm × 6 mm, 84-ball CSP_BGA package.
