These functions allow receipt of synchronous data from a patible transmitter, such as the SN75LVDS83B, over five balanced-pair conductors, and expansion to 28 bits of single-ended low-voltage TTL (LVTTL) synchronous data at a lower transfer rate. The SN75LVDS82 can also be used with the SN75LVDS84 for 21-bit transfers. When receiving, the high-speed LVDS data is received and loaded into registers at the rate of seven times (7×) the LVDS input clock (CLKIN). The data is then unloaded to a 28-bit-wide LVTTL parallel bus at the CLKIN rate. A phase-locked loop (PLL) 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 SN75LVDS82 requires only five line-termination resistors...
