Product Details

The LTC2000 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.

Additional features such as pattern generation, LVDS loopout and junction temperature sensing simplify system development and testing.

A serial peripheral interface (SPI) port allows configuration and read back of internal registers. Operating from 1.8V and 3.3V supplies, the LTC2000 consumes 2.2W at 2.5Gsps and 1.3W at 1.25Gsps.
