description

The SN75LVDS84A and SN65LVDS84AQ FlatLink transmitters contains three 7-bit parallel-load serial-out shift

registers, and four low-voltage differential signaling (LVDS) line drivers in a single integrated circuit. These

functions allow 21 bits of single-ended LVTTL data to be synchronously transmitted over 3 balanced-pair

conductors for receipt by a compatible receiver, such as the SN75LVDS82 or SN75LVDS86/86A.

When transmitting, data bits D0 – D20 are each loaded into registers of the ’LVDS84A upon the falling edge.

The internal PLL is frequency-locked to CLKIN and then used to unload the data registers in 7-bit slices. The

three serial streams and a phase-locked clock (CLKOUT) are then output to LVDS output drivers. The frequency

of CLKOUT is the same as the input clock, CLKIN.
