Product Summary
The DS90CR215MTD is a 3.3V rising edge data strobe LVDS with 21-bit channel link. The DS90CR215MTD transmitter converts 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signaling) data streams. A phase-locked transmit clock of the DS90CR215MTD 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. The DS90CR215MTD receiver converts the LVDS data streams back into 21 bits of CMOS/TTL data. At a transmit clock frequency of 66 MHz, 21 bits of TTL data are transmitted at a rate of 462 Mbps per LVDS data channel. Using a 66 MHz clock, the data throughput is 1.386 Gbit/s (173 Mbytes/s).
