www.ti.com SNLS226A – OCTOBER 2006 – REVISED FEBRUARY 2013 DS90CR217 +3.3V Rising Edge Data Strobe LVDS 21-Bit Channel Link -85 MHz
Check for Samples: DS90CR217 FEATURES DESCRIPTION The DS90CR217 transmitter converts 21 bits of
CMOS/TTL data into three LVDS (Low Voltage
Differential Signaling) data streams. A phase-locked
transmit clock is transmitted in parallel with the data
streams over a fourth LVDS link. Every cycle of the
transmit clock 21 bits of input data are sampled and
transmitted. At a transmit clock frequency of 85 MHz,
21 bits of TTL data are transmitted at a rate of 595
Mbps per LVDS data channel. Using a 85 MHz clock,
the data throughput is 1.785 Gbit/s (223 Mbytes/sec). 1 2 20 to 85 MHz Shift Clock Support
