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. The device comes in a 64-pin CFP package (10.9mm x 10.9mm) and supports a temperature range from –55°C to +105°C.

(1) For more information, see Section 12.
(2) These units are intended for engineering evaluation only. They are not put through a compliant flow (so there is no burn-in, only 25°C testing, etc.). Additionally, these units are not suitable for qualification, production, radiation testing, or flight use. The parts are not warranted for performance over temperature or operating life.
