3 Description

The ADC3564 device is a low-noise, ultra-low power,

14-bit, 125-MSPS, high-speed ADC. Designed for

low power consumption, the device delivers a noise

spectral density of –156 dBFS/Hz combined with

excellent linearity and dynamic range. The ADC3564

offers IF sampling support which makes the device

suited for a wide range of applications. High-speed

control loops benefit from the short latency of as little

as one clock cycle. The ADC consumes only 137 mW

at 125 MSPS, and the power consumption scales well

with lower sampling rates.

The ADC3564 uses serial LVDS (SLVDS) interface

to output the data which minimizes the number of

digital interconnects. The device supports two-lane,

one-lane and half-lane options. The device is a pinto-

pin compatible family with different speed grades

and comes in a 40-pin VQFN package. The device

supports the extended industrial temperature range

from –40 to +105⁰C.
