Description: | +3.3V Rising Edge Data Strobe LVDS 21-Bit Channel Link - 85 MHz |
Manufacturer: | National Semiconductor |
Datasheet: | PDF (623K). Click here to download *) |
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. |
