DESCRIPTION

The SN65LVDS93 LVDS serdes (serializer/

deserializer) transmitter contains four 7-bit parallelload

serial-out shift registers, a 7 נclock synthesizer,

and five low-voltage differential signaling (LVDS)

drivers in a single integrated circuit. These functions

allow 28 bits of single-ended LVTTL data to be

synchronously transmitted over five balanced-pair

conductors for receipt by a compatible receiver, such

as the SN65LVDS94.

When transmitting, data bits D0 through D27 are

each loaded into registers upon the edge of the input

clock signal (CLKIN). The rising or falling edge of the clock can be selected via the clock select (CLKSEL)

pin. The frequency of CLKIN is multiplied seven times

and then used to serially unload the data registers in

7-bit slices. The four 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.
