ADC32RF80, ADC32RF83

SBAS774A –MAY 2016–REVISED DECEMBER 2016

ADC32RF8x Dual-Channel, 3-GSPS Telecom Receiver and Feedback Devices

1 Features

3 Description

The ADC32RF8x (ADC32RF80 and ADC32RF83) is

a 14-bit, 3-GSPS, dual-channel telecom receiver and

feedback device family that supports RF sampling

with input frequencies up to 4 GHz and beyond.

Designed for high signal-to-noise ratio (SNR), the

ADC32RF8x family delivers a noise spectral density

of –155 dBFS/Hz as well as dynamic range and

channel isolation over a large input frequency range.

The buffered analog input with on-chip termination

provides uniform input impedance across a wide

frequency range and minimizes sample-and-hold

glitch energy.

•

14-Bit, Dual-Channel, 3-GSPS ADC

Noise Floor: –155 dBFS/Hz

•

RF Input Supports Up to 4.0 GHz

Aperture Jitter: 90 f_S

Channel Isolation: 95 dB at f_IN= 1.8 GHz

Spectral Performance (f_IN= 900 MHz, –2 dBFS):

–

SNR: 60.1 dBFS

SFDR: 66-dBc HD2, HD3

SFDR: 76-dBc Worst Spur

•

Spectral Performance (f_IN= 1.85 GHz, –2 dBFS):

Each channel can be connected to a dual-band,

digital down-converter (DDC) with up to three

independent, 16-bit numerically-controlled oscillators

(NCOs) per DDC for phase-coherent frequency

hopping. Additionally, the ADC is equipped with front-

end peak and RMS power detectors and alarm

functions to support external automatic gain control

(AGC) algorithms.

–

SNR: 58.9 dBFS

SFDR: 67-dBc HD2, HD3

SFDR: 76-dBc Worst Spur

On-Chip Digital Down-Converters:

–

Up to 4 DDCs (Dual-Band Mode)

Up to 3 Independent NCOs per DDC

•

On-Chip Input Clamp for Overvoltage Protection

The ADC32RF8x supports the JESD204B serial

interface with subclass 1-based deterministic latency

using data rates up to 12.5 Gbps with up to four lanes

per ADC. The device is offered in a 72-pin VQFN

package (10 mm × 10 mm) and supports the

industrial temperature range (–40°C to +85°C).

Programmable On-Chip Power Detectors with

Alarm Pins for AGC Support
