DS90CR218 +3.3V Rising Edge Data Strobe LVDS 21-Bit Channel Link Receiver - 75 MHz May 2002 DS90CR218 +3.3V Rising Edge Data Strobe LVDS 21-Bit Channel Link Receiver - 75 MHz General Description The DS90CR217 (see DS90CR217/218A datasheet) transmitter converts 21 bits of CMOS/TTL data into three LVDS (Low Voltage Differential Signaling) data streams. A phaselocked 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. The DS90CR218 receiver converts the three LVDS data streams back into 21 bits of CMOS/TTL data. At a transmit clock frequency of 75 MHz, 21 bits of TTL...
