ADC3664 14-Bit, 125-MSPS, Low-Noise, Low Power Dual Channel ADC

1 Features

3 Description

•

14-Bit 125 MSPS ADC

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

14-bit, 125-MSPS, high-speed dual channel ADC.

Designed for lowest noise performance, the device

delivers a noise spectral density of –156.9 dBFS/Hz

combined with excellent linearity and dynamic range.

The ADC3664 offers IF sampling support which

makes the device ideally suited 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 100 mW/ch at 125 MSPS and its

power consumption scales very well with lower

sampling rates.

Noise floor: –156.9 dBFS/Hz

Low power consumption: 100 mW/ch

Latency: 2 clock cycles

Voltage Reference:

– External: 65 to 125 MSPS

– Internal: 100 to 125 MSPS

Guaranteed 14-Bit, no missing codes

Input bandwidth: 1.4 GHz (3 dB)

INL: ±2.6 LSB; DNL: ±0.9 LSB

Industrial temperature Range: –40°C to +105°C

On-chip digital filter (optional)

– Decimation by 2, 4, 8, 16, 32

– 32-bit NCO

Serial LVDS digital interface (2-, 1- and 1/2-wire)

Small Footprint: 40-VQFN (5 mm × 5 mm)

Package

Spectral performance (f_IN= 5 MHz):

– SNR: 77.5 dBFS

•

The ADC3664 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 ADC3664 is pin-to-

pin compatible with a family of 16-bit resolution ADCs.

The device supports the extended industrial

temperature range from –40 to +105⁰C.
