DESCRIPTION
The SN65LVDS96 LVDS serdes (serializer/deserializer) receiver contains three serial-in 7-bit parallel-out shift
registers, a 7× clock synthesizer, and four low-voltage differential signaling (LVDS) line receivers in a single
integrated circuit. These functions allow receipt of synchronous data from a compatible transmitter, such asthe
SN65LVDS95, over four balanced-pair conductors and expansion to 21 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 of seven times the
LVDS input clock (CLKIN). The data is then unloaded to a 21-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 SN65LVDS96 presents valid data on the rising edge of the output clock (CLKOUT).
The SN65LVDS96 requires only four line termination resistors for the differential inputs and little or no control.
The data bus appears the same at the input to the transmitter and output of the receiver with data transmission
transparent to the user(s). The only user intervention is the possible use of the shutdown/clear (SHTDN)
active-low input to inhibit the clock and shut off the LVDS receivers for lower power consumption. A low level on
this signal clears all internal registers to a low level.
The SN65LVDS96 is characterized for operation over ambient air temperatures of –40°C to 85°C.
