Individual channel power-down is supported. The AD9655

typically consumes less than 2 mW in serial port interface (SPI)

power-down mode. The available digital test pat-terns include

built-in deterministic and pseudorandom patterns, along with

custom user-defined test patterns entered via the SPI.

GENERAL DESCRIPTION

The AD9655 is available in an RoHS-compliant, 32-lead LFCSP.

It is specified over the industrial temperature range of −40°C to

+85°C. This device is protected by a U.S. patent.

The AD9655 is a dual, 16-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.

PRODUCT HIGHLIGHTS

1. Small Footprint.

Two ADCs are contained in a small, space-saving package.

2. Pin Compatible.

The ADC requires a single 1.8 V power supply and an LVPECL-/

CMOS-/LVDS-compatible sample rate clock for full performance

operation. External reference or driver components are not

required for many applications.

The AD9655 is pin compatible to the AD9645 14-bit and

AD9635 12-bit dual ADCs.

3. Ease of Use.

A DCO operates at frequencies of up to 500 MHz and

supports double data rate (DDR) operation.

4. User Flexibility.

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.

The SPI control offers a wide range of flexible features to

meet specific system requirements.
