Abstract :
The S-Interface chip (SIC) is a transceiver circuit able to interface voice/data communication equipment to the 4-wire CCITT S-bus. The device can be configured to operate either in TE (Terminal Equipment), NT (Network Termination) or as a PABX line card device. The 5-volt 22-pin chip is implemented in a 2¿m-CM0S technology. Power consumption is less than 60 mW in active operation and 5 mW in power down mode.
