DESCRIPTION
The SN75LVDS82 FlatLink™ 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 SN75LVDS81,
over five balanced-pair conductors, and expansion to 28 bits of single-ended low-voltage TTL (LVTTL)
synchronous data at a lower transfer rate. The SN75LVDS82 can also be used with the SN75LVDS84 or
SN75LVDS85 for 21-bit transfers.
When receiving, the high-speed LVDS data is received and loaded into registers at the rate of seven times (7×)
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 (PLL) clock synthesizer circuit generates a 7× clock for internal clocking and an output clock
for the expanded data. The SN75LVDS82 presents valid data on the falling edge of the output clock (CLKOUT).
