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; the AD9645 typically consumes less

than 2 mW in the full power-down state. The ADC provides

several features designed to maximize flexibility and minimize

system cost, such as programmable output clock and data align-

ment 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 AD9645 is available in a RoHS-compliant, 32-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.

GENERAL DESCRIPTION

PRODUCT HIGHLIGHTS

The AD9645 is a dual, 14-bit, 80 MSPS/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.

1. Small Footprint. Two ADCs are contained in a small, space-

saving package.

2. Low Power. The AD9645 uses 122 mW/channel at 125 MSPS

with scalable power options.

3. Pin Compatibility with the AD9635, a 12-Bit Dual 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.

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.

5. User Flexibility. SPI control offers a wide range of flexible

features to meet specific system requirements.
