The SN75LVDS84DGG is a FlatLink Transmitter contains three 7-bit parallel-load serial-out shift registers, a 7x clock synthesizer and four low-voltage differential signalling (LVDS) line drivers in a single integrated circuit. This function allows 21-bits of single-ended low-voltage TTL (LVTTL) data to be synchronously transmitted over three balanced-pair conductors for receipt by a compatible receiver, such as the SN75LVDS82 or SN75LVDS86. When transmitting, data bits D0-D20 are each loaded into registers of the SN75LVDS84 on the falling edge of the input clock signal (CLKIN). The frequency of CLKIN is multiplied seven times and then used to unload the data registers in 7-bit slices and serially. 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. It requires no external components and little or no control.
