The SN75LVDS83 FlatLink transmitter contains
28
29
four 7-bit parallel-load serial-out shift registers, a
7× clock synthesizer, and five low-voltage
differential-signaling (LVDS) line drivers in a single integrated circuit. These functions allow 28 bits of
single-ended low-voltage TTL (LVTTL) data to be synchronously transmitted over five balanced-pair conductors
for receipt by a compatible receiver, such as the SN75LVDS82. The SN75LVDS83 can also be used in 21-bit
links with the SN75LVDS86 receiver.
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 by way of the clock select (CLKSEL)
terminal. The frequency of CLKIN is multiplied seven times (7×) and then used to unload the data registers in
7-bit slices and serially. 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.
The SN75LVDS83 requires no external components 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. 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 output drivers for lower power consumption. A low-level signal on SHTDN clears all
internal registers to a low level.
The SN75LVDS83 is characterized for operation over free-air temperature ranges of 0_C to 70_C.
