3V Rising Edge Data Strobe LVDS 21-Bit Channel Link - 85 MHz Check for Samples: DS90CR217 FEATURES 1 •2 20 to 85 MHz Shift Clock Support • 50% Duty Cycle on Receiver Output Clock • Best-in-Class Set & Hold Times on TxINPUTs • Low Power Consumption • ±1V Common-Mode Range (Around +1.
2V) • Narrow Bus Reduces Cable Size and Cost • Up to 1.
785 Gbps Throughput • Up to 223 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 48-Lead TSSOP Package 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).
The narrow bus and LVDS signalling of the DS90CR217 is an ideal means to solve EMI and cable size problems associated with wide, high-speed TTL interfaces.
