DESCRIPTION
Positive Supply Voltage. Bypasses to Vss with 0
.1 μF capacitor.
Receive Analog Input. Analog input from the telephone network.
Capacitor. Connect a 0.1μF capacitor between Pin 3 and ground (VSS).
Filtered Receive Analog Input
Analog Input Control. A logical 1 selects the filtered input. A logical 0 selects
the non-filtered input.
Self-Test Mode Control. Normal operation when a logical 0.A logical 1 places
the device into the self-test mode. A low appears at RXD, to indicate a
properly functioning device.
Transmitter Control. A logical 0 selects transmit mode. A logical 1 selects a
stand-by condition forcing TXA to VDD/2 VDC.
Ground
Synchronous Clock Output. Digital output synchronized with the 1200 bit/s
received data when
6<1LVORZ
and used to sample the received data or eye
pattern. The falling edge of SYNC should be used to sample RXD. When

Sync Enable. A logic 0 locks the SYNC clock PLL to the 1200 baud receive
data. A logic 1 disables the receive data PLL, and connects SYNC to the 1200
HZ reference.
