GENERAL DESCRIPTION
The AD9653 is a quad, 16-bit, 125 MSPS analog-to-digital con-
verter (ADC) with an on-chip sample-and-hold circuit
designed for low cost, low power, small size, and ease of use.
The product operates at a conversion rate of up to 125 MSPS
and is optimized for outstanding dynamic performance and low
power in applications where a small package size is critical.
The ADC requires a single 1.8 V power supply and LVPECL-/
CMOS-/LVDS-compatible sample rate clock for full performance
operation. No external reference or driver components are
required for many applications.
The ADC automatically multiplies the sample rate clock for the
appropriate LVDS serial data rate. A data clock output (DCO) for
capturing data on the output and a frame clock output (FCO)
for signaling a new output byte are provided. Individual-channel
power-down is supported and typically consumes less than 2 mW
when all channels are disabled. The ADC contains several features
designed to maximize flexibility and minimize system cost, such

as programmable output clock and data alignment and digital
test pattern generation. The available digital test patterns
include built-in deterministic and pseudorandom patterns, along
with custom user-defined test patterns entered via the serial port
interface (SPI).
The AD9653 is available in a RoHS-compliant, 48-lead LFCSP.
It 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. Small Footprint.
Four ADCs are contained in a small, space-saving package.
2. Low power of 164 mW/channel at 125 MSPS with scalable
power options.
3. Pin compatible to the AD9253 14-bit quad and the AD9633
12-bit quad ADC.
4. Ease of Use.
A data clock output (DCO) operates at frequencies of up to
500 MHz and supports double data rate (DDR) operation.
5. User Flexibility.
The SPI control offers a wide range of flexible features to
meet specific system requirements.
