DESCRIPTION

The SN65LVDS94 LVDS serdes (serializer/deserializer) receiver contains four serial-in 7-bit parallel-out shift

registers, a 7× clock synthesizer, and five low-voltage differential signaling (LVDS) line receivers in a single

integrated circuit. These functions allow receipt of synchronous data from a compatible transmitter, such as the

SN65LVDS93 and SN65LVDS95, over five balanced-pair conductors and expansion to 28 bits of single-ended

LVTTL synchronous data at a lower transfer rate.

When receiving, the high-speed LVDS data is received and loaded into registers at the rate seven times the

LVDS input clock (CLKIN). The data is then unloaded to a 28-bit wide LVTTL parallel bus at the CLKIN rate. A

phase-locked loop clock synthesizer circuit generates a 7× clock for internal clocking and an output clock for the

expanded data. The SN65LVDS94 presents valid data on the rising edge of the output clock (CLKOUT).
