GENERAL DESCRIPTION

The AD9643 is a dual, 14-bit analog-to-digital converter (ADC)

with sampling speeds of up to 250 MSPS. The AD9643 is designed

to support communications applications, where low cost, small

size, wide bandwidth, and versatility are desired.

The AD9643 is available in a 64-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.

The dual ADC cores feature a multistage, differential pipelined

architecture with integrated output error correction logic. Each

ADC features wide bandwidth inputs supporting a variety of

user-selectable input ranges. An integrated voltage reference

eases design considerations. A duty cycle stabilizer is provided

to compensate for variations in the ADC clock duty cycle,

allowing the converters to maintain excellent performance.

PRODUCT HIGHLIGHTS

1. Integrated dual, 14-bit, 170 MSPS/210 MSPS/250 MSPS ADCs.

2. Operation from a single 1.8 V supply and a separate digital

output driver supply accommodating LVDS outputs.

3. Proprietary differential input maintains excellent SNR

performance for input frequencies of up to 400 MHz.

4. SYNC input allows synchronization of multiple devices.

5. 3-pin, 1.8 V SPI port for register programming and register

readback.

The ADC output data is routed directly to the two external

14-bit LVDS output ports and formatted as either interleaved or

channel multiplexed.

6. Pin compatibility with the AD9613, allowing a simple

migration down from 14 bits to 12 bits. This part is also pin

compatible with the AD6649 and the AD6643.

Flexible power-down options allow significant power savings,

when desired.
