These five outputs are 5B encoded transmit data sym bols, driven at the rising edge of LSCLK. TDAT4 is the Most Significant Bit. Local Synchrnous Clock. This pin supplies the frequency reference to the MX98745 within same HUB. It should be driven by a crystal- controlled 25M clock source. Receive Data. These 5 bit parallel data symbol from transceiver are latched by the rising edge of RSCLK of each port. RDAT4 is the Most Significant Bit. Recovered Symbol Clock. This is a 25 MHz clock, which is derived from the clock synchronization PLL circuit. Signal Detect. This signal indicates that the received signal is above the detection threshold and will be used for the link test state machine. Monitor Mode. Internal Pulldown. When this pin is set to one, LED display pins LED[9:0] will be changed to monitor mode. Table 5-1 Pin Description for XRCII P/N:PM0427 REV. 1.4, JUL. 8, 1998 4
