APPLICATIONS

The ADC output data is routed directly to the JESD204A serial

output port. This output is at CML voltage levels. A CMOS or

LVDS synchronization input (DSYNC) is provided.

Communications

Diversity radio systems

Multimode digital receivers (3G and 4G)

GSM, EDGE, W-CDMA, LTE,

CDMA2000, WiMAX, TD-SCDMA

Smart antenna systems

General-purpose software radios

Broadband data applications

Ultrasound equipment

The flexible power-down options allow significant power savings,

when desired.

Programming for setup and control is accomplished using a 3-wire

SPI-compatible serial interface.

The AD9641 is available in a 32-lead LFCSP and is specified over

the industrial temperature range of −40°C to +85°C.

This product is protected by a U.S. patent.

GENERAL DESCRIPTION

The AD9641 is a 14-bit, 80 MSPS/155 MSPS analog-to-digital

converter (ADC) with a high speed serial output interface. The

AD9641 is designed to support communications applications

where high performance, combined with low cost, small size, and

versatility, is desired. The JESD204A high speed serial interface

reduces board routing requirements and lowers pin count

requirements for the receiving device.

PRODUCT HIGHLIGHTS

1. An on-chip PLL allows users to provide a single ADC

sampling clock. The PLL multiplies the ADC sampling clock

to produce the corresponding JESD204A data rate clock.

2. The configurable JESD204A output block coded data rate

supports up to 1.6 Gbps.

3. A proprietary differential input maintains excellent SNR

performance for input frequencies of up to 250 MHz.

4. Operation is from a single 1.8 V power supply.

5. The standard serial port interface (SPI) supports various

product features and functions, such as data formatting

(offset binary, twos complement, or Gray coding), control-

ling the clock DCS, power-down, test modes, voltage

reference mode, and serial output configuration.

The ADC core features a multistage, differential pipelined

architecture with integrated output error correction logic. The

ADC features wide bandwidth, differential sample-and-hold,

analog input amplifiers that support a variety of user-selectable

input ranges. An integrated voltage reference eases the design

considerations. A duty cycle stabilizer (DCS) is provided to

compensate for variations in the ADC clock duty cycle,

allowing the converter to maintain excellent performance.
