Part Number : DS90CR288MTD
Function : LVDS 28-Bit Channel Link Receiver – 75 MHz
Package : 56 TSSOP Type
Manufacturers : Texas Instruments
The DS90CR287, DS90CR288MTD transmitter converts 28 bits of CMOS/TTL 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 DS90CR288 receiver converts the four LVDS data streams back into 28 bits of CMOS/TTL data. At a transmit clock frequency of 75 MHz, 28 bits of TTL data are transmitted at a rate of 525 Mbps per LVDS data channel. Using a 75 MHz clock, the data throughput is 2.10 Gbit/s (262.5 Mbytes/sec).
C The DS90CR287 supports clock rates from 20 to 85 MHz.
This chipset is an ideal means to solve EMI and cable size problems associated with wide, high-speed TTL interfaces.
