AD9253TCPZ-125EP The AD9253-EP is a quad, 14-bit, 125 MSPS analog-to-digital

converter (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 AD9253-EP is available in a RoHS-compliant, 48-lead LFCSP

and is specified over an extended temperature range of −55°C to

+125°C. This product is protected by a U.S. patent. Additional

application and technical information can be found in the AD9253

data sheet.
