3 Description

The SN65LVDS93B LVDS SerDes

(serializer/deserializer) transmitter contains four 7-bit

parallel load serial-out shift registers, a 7 × clock

synthesizer, and five low-voltage differential signaling

(LVDS) drivers in a single integrated circuit. These

functions allow synchronous transmission of 28 bits of

single-ended LVTTL data over five balanced-pair

conductors for receipt by a compatible receiver, such

as the DS90CR286A and 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 through 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.
