3 Description

The ADC3664-xEP device is a low-noise, ultra-low

power, 14-bit, 125MSPS, high-speed dual channel

ADC. Designed for lowest noise performance,

the device delivers a noise spectral density of

-156.9dBFS/Hz combined with linearity and dynamic

range. The ADC3664-xEP offers IF sampling support

which makes the device designed for a wide range

of applications. High-speed control loops benefit from

the short latency as low as one clock cycle. The

ADC consumes only 100mW/ch at 125MSPS, and the

power consumption scales well with lower sampling

rates.

The ADC3664-xEP uses a serial LVDS (SLVDS)

interface to output the data which minimizes the

number of digital interconnects. The device supports

a two-lane, one-lane and half-lane option. The device

supports an extended temperature range from –55°C

to +105°C.
