The SN65LVDS86A FlatLink™ receiver contains three serial-in 7-bit parallel-out shift registers 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 as the SN75LVDS81, '83, '84, or '85, over four balanced-pair conductors and expansion to 21 bits of single-ended low-voltage LVTTL synchronous data at a lower transfer rate.
When receiving, the high-speed LVDS data is received and loaded into registers at seven times the LVDS input clock (CLKIN) rate. The data is then unloaded to a 21-bit wide LVTTL parallel bus at the CLKIN rate. The SN65LVDS86A presents valid data on the falling edge of the output clock (CLKOUT).
