GENERAL DESCRIPTION

The

sampling speeds of up to 250 MSPS. The

support communications applications where low cost, small size,

wide bandwidth, and versatility are desired.

The ADC core features a multistage, differential pipelined

architecture with integrated output error correction logic. The

ADC features wide bandwidth inputs that can support a variety

of user-selectable input ranges. An integrated voltage reference

eases design considerations. A duty cycle stabilizer (DCS) is

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

allowing the converter to maintain excellent performance.

The ADC output data are routed directly to the external 12-bit

LVDS output port.

Flexible power-down options allow significant power savings,

when desired.
