DS90CR288AMTD/NOPB Datasheet

LVDS Interface IC


The DS90CR288AMTD/NOPB 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.The DS90CR288AMTD/NOPB receiver converts the four LVDSdata streams back into 28 bits of LVCMOS/LVTTL data. At a transmit clock frequency of 85 MHz, 28 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 2.38 Gbitls (297.5 Mbytes/sec). This chipset is an ideal means to solve EMI and cable size problems associated with wide, high-speed TTL interfaces. DS90CR288AMTD/NOPB Features • 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• 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
