Dual-Channel, 250-MSPS Feedback Receiver IC

Check for Samples: ADS62PF49

FEATURES

DESCRIPTION

The ADS62PF49 is a dual-channel feedback reciever

IC with sampling rates up to 250 MSPS. It allows a

•

Maximum Output Sample Rate: 250 MSPS

Pin-Compatible with ADS62P49

Variable Output Resolution

high-resolution, 14-bit output for

a limited time

followed by a low-resolution mode with a minimum of

8x longer time. It is pin-compatible to the ADS62P49

and ADS62C17 dual ADCs.

–

High Resolution Burst Mode with 14-Bit

Output: 73 dB SNR at Low IF,

70.5 dB SNR at 170 MHz

The ADS62PF49 has gain options that can be used

to improve SFDR performance at lower full-scale

input ranges. It includes a dc offset correction loop

that can be used to cancel the analog-to-digital

conversion (ADC) offset.

–

Low Resolution with 9-Bit 250 MSPS or

11-Bit 125 MSPS

•

Double Data Rate (DDR) LVDS Output

Programmable Gain up to 6 dB for SNR/SFDR

Trade-off

90-dB Cross-Talk

Power Consumption of 1.25 W

64-Pin QFN Package (9 mm × 9 mm)

It includes internal references while the traditional

reference pins and associated decoupling capacitors

have been eliminated. The device is specified over

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