Product Summary

The DS90CR485VS is a 133MHz 48-bit Channel Link Serializer. It serializes the 24 LVCMOS/LVTTL double edge inputs (48 bits data latched in per clock cycle) onto 8 Low Voltage Differential Signaling (LVDS) streams. A phaselocked transmit clock of the DS90CR485VS is also in parallel with the data streams over a 9th LVDS link. The reduction of the wide TTL bus to a few LVDS lines reduces cable and connector size and cost. The double edge input of the DS90CR485VS strobes data on both the rising and falling edges of the clock. This minimizes the pin count required and simplifies PCB routing between the host chip and the serializer.
