170-Lead (9mm Г— 15mm) BGA Package The LTCВ®2000A 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 …
