A/D Converter
Atmel® announces a 10-bit A/D converter with a clock frequency of 1.5 Gs/s. The AT84AS003TP breaks the 8.0 ENOB barrier at sampling rates over 1 Gs/s. At 1.5 Gs/s, performance such as 8.0 ENOB, 58 dB SFDR has been demonstrated in Nyquist conditions. The 3 GHz analog input bandwidth allows operation in second Nyquist zone with performance at up to 1.5 GHz input frequency. The embedded, selectable 1:2 or 1:4 demultiplexer allows direct interfacing with standard LVDS compatible FPGAs, without any external circuitry required. Additionally, timing or voltage tuning is not necessary, even when sweeping the sampling frequency from 100 Ms/s to 1.5 Gs/s. Other features include selectable simultaneous or staggered output, gain adjust, sampling delay adjust, and embedded Built-in Self Test (BIST).
