Pin Function
PIN NUMBER
Pin Name I/O TYPE Description
DCD 2 Output DTE Data Carrier Detect output signal. Indicates modem has detected carrier.
RING 3 Input Ring detector input. This pin assumes that a half wave opto coupler is used in the
telephone line DAA circuit in the frequency detection algorithm.
RTS 4 Input DTE Ready To Send input signal. Used for hardware flow control.
DTR 5 Input DTE Data Terminal Ready input signal. Used to enable modem device
CS0 6 Intput Country Selection bit 0 (Internal pull up)
CS1 7 Input Country Selection bit 1 (Internal pull up)
CS2 8 Input Country Selection bit 2 (Internal pull up)
CS3 9 Input Country Selection bit 3 (Internal pull up)
RESET 10 Input Reset signal to the AMC2442A Controller. Active High.
TXD 11 Input DTE Transmit Data Pin. All data communication from the DTE connects via this pin.
RXD 13 Output DTE Receive Data Pin. All data communication to the DTE connects via this pin.
RXC 14 Input Receiver Clock Input from AFE. Used in PSK, QAM and synchronous data mode.
TXC 15 Input Transmitter Clock Input from AFE. Used in PSK, QAM and synchronous data mode.
Free 16 I/O DO NOT CONNECT
CTS 17 Output DTE Clear To Send output signal. Used for hardware flow control.
WR 18 Output Write signal to AFE. Goes active low whenever the SMC wishes to write to the AFE
RD 19 Output Read signal to AFE. Goes active low whenever the SMC wishes to read from the AFE
CLKo 20 Output Buffered Clock output signal. Also used as a crystal drive signal when required.
CLKi 21 Input Clock input signal. The SMC requires an 11.0592MHz signal on this pin.
GND 22 Power Controller Ground connection
SPKR 24 Output Speaker Enable drive
Free 25 I/O DO NOT CONNECT
Free 26 I/O DO NOT CONNECT
RLY 27 Output DAA Line Seize relay control. Used if DPCO relay is used to share the telephone with a
standard telephone instrument.
BS 28 Output DAA Bell Shunt control. Used during LD dialling to provide a low impedance loop.
SENSE 29 Input Line-In-Use detection input.
CHECK 30 Output Line-In-Use circuit drive pin.
HOOK 31 Output DAA Hook switch control. Delayed from Seize to allow for a low cost opto coupler.
NC 32 I/O DO NOT CONNECT
LATCH 33 Output ALE signal to AFE. Goes active high to latch an address into the AFE
VCC2 35 Power Auxiliary power supply pin.
AD7->AD0 36->43 I/O Multiplex Address / Data bus connections to AFE.
VCC1 44 Power Main power supply pin.
NC 1 I/O DO NOT CONNECT
NC 12 I/O DO NOT CONNECT
