LTC2000 Datasheet 16-/14-/11-bit 2.5gsps Dacs

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®2000 is a family of 16-/14-/11-bit 2.5Gsps current steering DACs with exceptional spectral purity.

The single (1.25Gsps mode) or dual (2.5Gsps mode) port source synchronous LVDS interface supports data rates of up to 1.25Gbps using a 625MHz DDR data clock, which can be either in quadrature or in phase with the data.

An internal synchronizer automatically aligns the data with the DAC sample clock.
