6 / 9 page 6 NWK914D Pin Name Pin Type Pin Number Pin Description SYMBOL Interface RXC TTLOP 4 25MHz recovered receive clock. This is aligned with and used to clock out the 5 bit parallel receive data to the PCS layer. SDT TTLOP 5 Signal detect output. This output is high when an input signal of sufficient amplitude is detected on the RXI inputs. TDAT4 TTLIP 40 The 100BASE-TX transmit input bit 4 TDAT3 TTLIP 41 The 100BASE-TX transmit input bit 3 TDAT2 TTLIP 42 The 100BASE-TX transmit input bit 2 TDAT1 TTLIP 43 The 100BASE-TX transmit input bit 1 TDAT0 TTLIP 44 The 100BASE-TX transmit input bit 0 TXC TTLOP 47 25MHz transmit clock. This is aligned with and used to clock in the 5 bit parallel 100BASE-TX transmit data from the PCS layer. RDAT0 TTLOP 48 The 100BASE-TX receive output bit 0 RDAT1 TTLOP 49 The 100BASE-TX receive output bit 1 RDAT2 TTLOP 50 The 100BASE-TX receive output bit 2 RDAT3 TTLOP 51 The 100BASE-TX receive output bit 3 RDAT4 TTLOP 52 The 100BASE-TX receive output bit 4 Network Interface RXIP analog input 15 + Differential receive signal input from magnetics RXIN analog input 16 – Differential receive signal input from magnetics TXON analog output 22 – Differential transmit line driver outputs to magnetics TXOP analog output 23 + Differential transmit line driver outputs to magnetics 10BASE-T Interface 10TXIN analog input 19 The filtered 10BASE-T transmit input (–) 10TXIP analog input 20 The filtered 10BASE-T transmit input (+) Control Pins N10/100 TTLIP 36 10/100 mode selection. A low selects the 10BASE-T mode and enables the data on pins 10TXIP/N to be outut on the TXOP/N pins. A high selects the 100BASE-TX mode, enabling the 100Mb/s drivers. EQSEL 3 level IP 18 Mode select input for equalizer. Normally this pin is left unconnected (floating) for auto-eq. mode. High selects minimum equalization. Low selects full equalization. LBEN TTLIP 35 Loopback enable input. A high on this pin selects the loopback mode and low selects normal operation. TXOE TTLIP 33 Transmit output enable. A high on this pin selects normal operation. A low on this pin puts both of the TX drivers in tri-state mode. TESTIP test 37 Test pin. This pin must be left unconnected for proper operation. TEST test 38 Test pin. This pin must be left unconnected for proper operation. N/C 2,3,7,8 No connection. This pin must be left unconnected for proper operation. Component Connections REFCLK TTLIP 45 25MHz clock input. An external 25MHz oscillator is input to this pin. TXREF analog input 25 TXOP/N line driver current setting pin. Connects to TXGND through a resistor. LFRB analog 10 Differential loop filter pin for receive PLL (see fig.6) LFRA analog 11 Differential loop filter pin for receive PLL (see fig.6) LFTB analog 30 Differential loop filter pin for transmit clock PLL (see fig.6) LFTA analog 31 Differential loop filter pin for transmit clock PLL (see fig.6) Power TTLGND Power 1,39 GND for TTL logic I/Os RDLV CC Power 6 +5V supply to receive logic RXPLLGND Power 9 GND to receive PLL RXPLLV CC Power 12 +5V supply to receive PLL RXV CC2 Power 13 +5V supply to adaptive equalizer and QFB circuits RXGND Power 14 GND to to adaptive equalizer and QFB circuits RXV CC1 Power 17 +5V supply to MLT-3 to NRZI converter TXV CC Power 21 +5V supply to transmit line driver circuits TXGND Power 24 GND to transmit line driver circuits RXV CC Power 26 +5V supply to on-chip bandgap reference SUBGND Power 27 Chip substrate GND connection BGAPGND Power 28 GND to on-chip bandgap reference TXPLLGND Power 29 GND to to transmit clock-multiplier PLL TXPLLV CC Power 32 +5V supply to transmit clock-multiplier PLL TDLV CC Power 34 +5V supply to transmit logic TXLV CC Power 46 +5V supply to TTL logic I/Os Table 1: Pin descriptions |
