GENERAL DESCRIPTION

The AD9239 is a quad, 12-bit, 250 MSPS analog-to-digital

converter (ADC) with an on-chip temperature sensor and a

high speed serial interface. It is designed to support digitizing

high frequency, wide dynamic range signals with an input

bandwidth up to 780 MHz. The output data are serialized and

presented in packet format, consisting of channel-specific

information, coded samples, and error correction code.

Fabricated on an advanced CMOS process, the AD9239 is avail-

able in a Pb-free/RoHS-compliant, 72-lead LFCSP package. It is

specified over the industrial temperature range of −40°C to +85°C.

PRODUCT HIGHLIGHTS

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

2. An on-chip PLL allows users to provide a single ADC

sampling clock, and the PLL distributes and multiplies up

to produce the corresponding data rate clock.

3. Coded data rate supports up to 4.0 Gbps per channel.

Coding includes scrambling to ensure proper dc common

mode, embedded clock, and error correction.

4. The AD9239 operates from a single 1.8 V power supply.

5. Flexible synchronization schemes and programmable

mode pins.

The ADC requires a single 1.8 V power supply and the input

clock may be driven differentially with a sine wave, LVPECL,

TTL, or LVDS. A clock duty cycle stabilizer allows high

performance at full speed with a wide range of clock duty

cycles. The on-chip reference eliminates the need for external

decoupling and can be adjusted by means of SPI control.

Various power-down and standby modes are supported. The

ADC typically consumes 145 mW per channel with the digital

link still in operation when standby operation is enabled.

6. On-chip temperature sensor.
