FEATURES
Single chip DS1 rate transceiver
Supports common framing standards
– 12 frames/superframe “193S”
– 24 frames/superframe “193E”
Three zero suppression modes
– B7 stuffing
– B8ZS
– Transparent
Simple serial interface used for config-
uration, control and status monitoring in
“processor” mode
=“Hardware” mode requires no host
processor; intended for stand-alone app-
lications
Selectable 0, 2, 4, 16 state robbed bit
signaling modes
Allows mix of “clear” and “non-clear” DS0
channels on same DS1 link
Alarm generation and detection
Receive error detection and counting for
transmission performance monitoring
5V supply, low-power CMOS technology
Surface-mount package available, designated
DS2180AQ
Industrial temperature range of -40°C to
+85°C available, designated DS2180AN or
DS2180AQN
Compatible to DS2186 Transmit Line
Interface, DS2187 Receive Line Interface,
DS2188 Jitter Attenuator, DS2175 T1/CEPT
Elastic Store, DS2290 T1 Isolation Stik, and
DS2291 T1 Long Loop Stik
