GENERAL DESCRIPTION
The TCC110 is a low power CMOS device used for receiving physical layer signals like Bellcore's CPE Alerting
Signal (CAS) and similar evolving systems. This device also meets the requirements of emerging Calller ID on
Call Waiting (CIDCW) services. In addition, two different signal inputs are available to support Tip/Ring and Hybrid
connectivity. The device also includes a 1200 baud Bell 202/V.23 compatible FSK data demodulator, a ring or line
reversal detector, a Progress Tone Energy detector, a DTMF generator and a DC line voltage level measurement
unit. The status of the TCC110, the received FSK data, the ring frequency and other received information can be
read and control options can be written via the serial interface. An on-chip 3.579545MHz oscillator is available. In
power-down mode only the ring or line reversal detector can be active. The operating voltage is 3V ~ 5V and the
device is available in a 24-pin SOP package.
