MD652D is a high-speed 12-bit Digital to Analog Converter (DAC) integrated with a 48:12 (12
channels of 4:1) input multiplexer. The converter can be operated at a sampling rate up to ~ 4.5
Gsps. The digital data inputs are LVDS with on-chip 100 ohm termination resistors. After the 48
pairs of differential data inputs were multiplexed up to 4 times of speed, the 12 high speed data
bits are latched and encoded to drive DAC output stage. To minimize the glitch energy and to
achieve high linearity, the DAC is based on a 4-bit segmented with 8-bit R-2R architecture.
Complementary outputs are available with 50-Ω output back terminations. Divided-by-4 clock
LVDS outputs and sampling phase selection (SEL1 and SEL2) are provided to ease the alignment
of sampling phase relative to the input data. Divided-by-8 clock LVDS outputs are also provided.
A RESET function is provided for system applications which need to synchronize the outputs
from multiple MD652D’s.
