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 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.
The ADC output data is routed directly to the two external
14-bit LVDS output ports and formatted as either interleaved or
channel multiplexed.
Flexible power-down options allow significant power savings,
when desired.
Programming for setup and control are accomplished using a
3-wire SPI-compatible serial interface.
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.
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.
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.
