Pin Sym IO Name Description 6,38, 52,82, 85,94, 105,139, 161,162 VD+ - +ve power supply Power supply, 4.75 - 5.25 Volts. 115 VA+ - +ve power supply Power supply for Clock Recovery PLL, 4.75 - 5.25 Volts. 5, 37, 51,81, 84,108, 122,123, 124,128, 130,138, 159,160 GND - Ground Power Supply 41 33 27 21 15 9 1 171 165 47 55 61 67 73 79 154 TPOS1 TPOS2 TPOS3 TPOS4 TPOS5 TPOS6 TPOS7 TPOS8 TPOS9 TPOS10 TPOS11 TPOS12 TPOS13 TPOS14 TPOS15 TPOS16 I Transmit Data Positive Transmit channel 1-16, corresponds to +ve in bipolar signal. 42 34 28 22 16 10 2 172 166 48 56 62 68 74 80 153 TNEG1 TNEG2 TNEG3 TNEG4 TNEG5 TNEG6 TNEG7 TNEG8 TNEG9 TNEG10 TNEG11 TNEG12 TNEG13 TNEG14 TNEG15 TNEG16 I Transmit Data Negative Transmit channel 1-16, corresponds to -ve in bipolar signal. 39 30 24 18 12 4 174 168 158 44 50 58 64 70 76 87 RPOS1 RPOS2 RPOS3 RPOS4 RPOS5 RPOS6 RPOS7 RPOS8 RPOS9 RPOS10 RPOS11 RPOS12 RPOS13 RPOS14 RPOS15 RPOS16 O Receive Data Positive Receive channel 1-16, corresponds to +ve in bipolar signal. Pin Sym IO Name Description 36 31 25 19 13 7 175 169 163 45 53 59 65 71 77 88 RNEG1 RNEG2 RNEG3 RNEG4 RNEG5 RNEG6 RNEG7 RNEG8 RNEG9 RNEG10 RNEG11 RNEG12 RNEG13 RNEG14 RNEG15 RNEG16 O Receive Data Negative Receive channel 1-16, corresponds to -ve in bipolar signal. 131 DCD O Data Carrier Detect When DCD=1, then the communicating modems have synchronised, and are communicating. 120 121 XTI/ XTO - System Clock Crystal Connect fundamental parallel resonance crystal with appropriate padding capacitor to GND. 129 PORB I Power On Reset Will initialise the device when PORB= 0. PORB is normally connected to an RC circuit so that a POR is automatically invoked on power-up. PORB= 1 for normal operation. 156 TmCLK I/O Transmit maintenance CLK Transmit maintenance Clock. samples TmD on edge selected by TRSEL control. 155 RmCLK O Receive maintenance Clock Receive maintenance Clock. samples RmD on edge selected by RESEL control.. 116 RESEL I Receive Edge Select When RESEL = 1, RPOS/RNEG and RmD data is valid on the rising edge of RCLK/RmCLK. When RESEL = 0, the data is valid on the falling edge of RCLK/RmCLK. 104 TRSEL I Transmit Edge Select When TRSEL = 0, TPOS/TNEG and TmD data is latched on the falling edge of TCLK/TmCLK. When TRSEL =1, the data is latched on the rising edge of TCLK/TmCLK. 95 TmD1 I Transmit maintenance Data NRZ maintenance channel. TmD is sampled on the TmCLK clock edge defined by TRSEL. 92 RmD2 O Receive maintenance Data NRZ maintenance channel. RmD is sampled on the RmCLK clock edge defined by RESEL. |
