GENERAL DESCRIPTION

The AD9656 is a quad, 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 device 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.

Individual channel power-down is supported and typically

consumes less than 14 mW when all channels are disabled. The

ADC contains several features designed to maximize flexibility

and minimize system cost, such as a programmable output

clock, 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 AD9656 is available in an RoHS-compliant, nonmagnetic,

56-lead LFCSP.

It is specified over the −40°C to +85°C industrial temperature

range. This product is protected by a U.S. patent.

PRODUCT HIGHLIGHTS

1. It has a small footprint. Four ADCs are contained in a small, 8

mm × 8 mm package.

2. An on-chip phase-locked loop (PLL) allows users to provide

a single ADC sampling clock; the PLL multiplies the ADC

sampling clock to produce the corresponding JESD204B

data rate clock.

3. The configurable JESD204B output block supports up to

6.4 Gbps per lane.

4. JESD204B output block supports one, two, and four lane

configurations.

5. Low power of 198 mW per channel at 125 MSPS, two lanes.

6. The SPI control offers a wide range of flexible features to

meet specific system requirements.
