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.
