FEATURES Dual 10-bit/12-bit, 100 MSPS ADC SNR = 67 dB, fIN = 30.1 MHz Dual 10-bit/12-bit, 170 MSPS DAC ACLR = 74 dBc 5 channels of analog auxiliary input/output Low power, <425 mW at maximum sample rates Supports full and half-duplex data interfaces Small 72-lead LFCSP lead-free package APPLICATIONS Wireless infrastructure Picocell, femtocell basestations Medical instrumentation Ultrasound AFE Portable instrumentation Signal generators, signal analyzers GENERAL DESCRIPTION The AD9961/AD9963 are pin-compatible, 10-/12-bit, low power MxFE® converters that provide two ADC channels with sample rates of 100 MSPS and two DAC channels with sample rates to 170 MSPS. These converters are optimized for transmit and receive signal paths of communication systems requiring low power and low cost. The digital interfaces provide flexible clocking options. The transmit is configurable for 1×, 2×, 4×, and 8× interpolation. The receive path has a bypassable 2× decimating low-pass filter. The AD9961 and AD9963 have five auxiliary analog channels. Three are inputs to a 12-bit ADC. Two of these inputs can be configured as outputs by enabling 10-bit DACs. The other two channels are dedicated outputs from two independent 12-bit DACs. The high level of integrated functionality, small size, and low power dissipation of the AD9961/AD9963 make them well- suited for portable and low power applications.

PRODUCT HIGHLIGHTS 1. High Performance with Low Power Consumption. The DACs operate on a single 1.8 V to 3.3 V supply. Transmit path power consumption is <100 mW at 170 MSPS. Receive path power consumption is <350 mW at 100 MSPS from 1.8 V supply. Sleep and power-down modes are provided for low power idle periods. 2. High Integration. The dual transmit and dual receive data converters, five channels of auxiliary data conversion and clock generation offer complete solutions for many modem designs. 3. Flexible Digital Interface. The interface mates seamlessly to most digital baseband processors. |
