description
The SN75LVDS82 FlatLink receiver contains four serial-in 7-bit parallel-out shift registers, a 7× clock synthesizer, and five low-voltage dif ferential signaling (LVDS) line receivers in a single integrated circuit. These functions allow receipt of synchronous data from a compatible transmitter, such as the SN75LVDS81, over five balanced-pair conductors and expansion to 28 bits of single-ended low-voltage TTL (L VTTL) synchronous data at a lower transfer rate. The SN75L VDS82 can also be used with the SN75L VDS84 or SN75LVDS85 for 21-bit transfers.
When receiving, the high-speed L VDS data is received and loaded into registers at the rate of seven times (7×) the L VDS input clock (CLKIN). The data is then unloaded to a 28-bit wide L VTTL parallel bus at the CLKIN rate. A phase-locked loop clock synthesizer circuit generates a 7× clock for internal clocking and an output clock for the expanded data. The SN75LVDS82 presents valid data on the falling edge of the output clock (CLKOUT).
The SN75L VDS82 requires only five line-termination resistors for the differential inputs 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 possible user intervention is the use of the shutdown/clear (SHTDN
) active-low input to inhibit the clock and shut off the LVDS receivers for lower power consumption. A
low-level on SHTDN
clears all internal registers to a low level.
The SN75LVDS82 is characterized for operation over ambient air temperatures of 0_C to 70_C.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
