GENERAL DESCRIPTION

The AD9250 is a dual, 14-bit ADC with sampling speeds of up

to 250 MSPS. The AD9250 is designed to support communications

applications where low cost, small size, wide bandwidth, and

versatility are desired.

The ADC cores feature a multistage, differential pipelined

architecture with integrated output error correction logic. The

ADC cores feature wide bandwidth inputs supporting a variety

of user-selectable input ranges. An integrated voltage reference

eases design considerations. A duty cycle stabilizer is provided

to compensate for variations in the ADC clock duty cycle, allowing

the converters to maintain excellent performance. The JESD204B

high speed serial interface reduces board routing requirements

and lowers pin count requirements for the receiving device.

By default, the ADC output data is routed directly to the two

JESD204B serial output lanes. These outputs are at CML voltage

levels. Four modes support any combination of M = 1 or 2 (single

or dual converters) and L = 1 or 2 (one or two lanes). For dual

ADC mode, data can be sent through two lanes at the maximum

sampling rate of 250 MSPS. However, if data is sent through

one lane, a sampling rate of up to 125 MSPS is supported.

Synchronization inputs (SYNCINB± and SYSREF±) are provided.

Flexible power-down options allow significant power savings,

when desired. Programmable overrange level detection is

supported for each channel via the dedicated fast detect pins.

Programming for setup and control are accomplished using a

3-wire SPI-compatible serial interface.

The AD9250 is available in a 48-lead LFCSP and is specified

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

product is protected by a U.S. patent.
