Clocking Solution Reference Design for GSPS ADCs

TIDA-00359

Design files

Overview

Low cost, high performance clocking solution for GSPS data converters. This reference design discusses the use of a TRF3765, a low noise frequency synthesizer, generating the sampling clock for a 4 GSPS analog-to-digital converter (ADC12J4000). Experiments demonstrate data sheet comparable SNR and SFDR performance.

Features

Frequency ranges from 300MHz to 4.8GHz
Low noise VCO ~ 133dBc/Hz
Low jitter: 0.35ps
This reference design is tested and includes an evaluation board, configuration software and User's Guide
