www.ti.com SNLS056G – OCTOBER 1999 – REVISED MARCH 2013 DS90CR287/DS90CR288A +3.3V Rising Edge Data Strobe LVDS
28-Bit Channel Link -85MHz
Check for Samples: DS90CR287, DS90CR288A FEATURES DESCRIPTION The DS90CR287 transmitter converts 28 bits of
LVCMOS/LVTTL data into four LVDS (Low Voltage
Differential Signaling) data streams. A phase-locked
transmit clock is transmitted in parallel with the data
streams over a fifth LVDS link. Every cycle of the
transmit clock 28 bits of input data are sampled and
transmitted. 1 20 to 85 MHz Shift Clock Support
50% Duty Cycle on Receiver Output Clock
2.5 / 0 ns Set & Hold Times on TxINPUTs
Low Power Consumption
В±1V Common-Mode Range (around +1.2V)
Narrow Bus Reduces Cable Size and Cost
Up to 2.38 Gbps Throughput
Up to 297.5 Mbytes/sec Bandwidth
345 mV (typ) Swing LVDS Devices for Low EMI
PLL Requires no External Components
Rising Edge Data Strobe
Compatible with TIA/EIA-644 LVDS Standard
Low Profile 56-Lead TSSOP Package The DS90CR288A receiver converts the four LVDS
data streams back into 28 bits of LVCMOS/LVTTL …
