GENERAL DESCRIPTION
The AD9644 is a dual, 14-bit, analog-to-digital converter (ADC)
with a high speed serial output interface and sampling speeds
of either 80 MSPS or 155 MSPS.
The AD9644 is designed to support communications appli-
cations 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.
The dual ADC core features a multistage, differential pipelined
architecture with integrated output error correction logic. Each
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 design consid-
erations. A duty cycle stabilizer is provided to compensate for
variations in the ADC clock duty cycle, allowing the converters
to maintain excellent performance.
By default, the ADC output data is routed directly to the two
external JESD204A serial output ports. These outputs are at CML
voltage levels. Two modes are supported such that output coded
data is either sent through one data link or two. (L = 1; F = 4 or
L = 2; F = 2). Independent synchronization inputs (DSYNC) are
provided for each channel.
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 AD9644 is available in a 48-lead LFCSP and is specified over
the industrial temperature range of 40°C to +85°C.
