Product Details

The LTC2000A is a family of 16-/14-/11-bit 2.7Gsps current steering DACs with exceptional spectral purity.

The single (1.35Gsps mode) or dual (2.7Gsps mode) port source synchronous LVDS interface supports data rates of up to 1.35Gbps using a 675MHz 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 1.86V and 3.3V supplies, the LTC2000A consumes 2.41W at 2.7Gsps and 1.43W at 1.35Gsps.

Applications

  • Broadband Communication Systems
  • DOCSIS CMTS
  • Direct RF Synthesis
  • Radar
  • Instrumentation
