3 Description

The ADC3664-SP is a low latency, low noise, and

ultra low power, 14-bit, 125MSPS, high-speed dual

channel ADC. Designed for best noise performance,

the device delivers a noise spectral density of –

156.9dBFS/Hz combined with excellent linearity and

dynamic range. The ADC3664-SP offers DC precision

together with IF sampling support to enable the

design of a wide range of applications. The low

latency architecture (as low as 1 clock cycle latency)

and high sample rate also enable high speed

control loops. The ADC consumes only 100mW/ch

at 125MSPS and the power consumption scales well

with sampling rate.

The device uses a serial LVDS (SLVDS) interface to

output the data which minimizes the number of digital

interconnects. The device also integrates a digital

down converter (DDC) to help reduce the data rate

and lower system power consumption. The device

is pin-to-pin compatible with the 18-bit, 65MSPS

ADC3683-SP. It comes in a 64-pin CFP package

(10.9mm x 10.9mm) and supports a temperature

range from –55°C to +105°C.
