... OST INGLE OVERVIEW ICM7101D is a single chip telephone CMOS integrated circuits that meets multiple PTT requirements, allowing phone manufacturers to have single board design for various countries. This reduces inventory and simplify manufacturing processes. ICM7101D integrates dialer, speech, and ringer component counts, hence increases product reliability ...

... ICM7101D stays in shutdown mode so long as HS/DPB pin stays LOW. However, the ringer circuitry is activated in this mode to monitor the incoming ringing signal. OSCILATOR All the timing of ICM7101D is based on a clock frequency of 3.58 MHz. A Crystal or ceramic resonator of this frequency connected to oscilator pins of ICM7101D. Care ...
