DESCRIPTION

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).

The SN65LVDS86A 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 the 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 SN65LVDS86A is characterized for operation over the full automotive temperature range of –40°C to 125°C.
