FUNCTIONAL BLOCK DIAGRAM
FUNCTION DESCRIPTIONS
The EM92546 is a CMOS device designed to support the Caller Number Deliver feature which is offered by the
Regional Telephone Companies.The EM92546 CLID has a signal path. The signal path consist of an input
differential buffer,a band pass filter, an FSK demodulator and a data valid with carrier detect circuit.
A /PWUP input pin is provided to activate the chip accompanying with clock input to CLKIN. If /PWR UP is sent
high, the IC will be stayed at power down mode.

This input is connected to the tip line of the twisted pair.
This input is connected to the ring line of the twisted pair.
This active low input sets the chip into power up.
When high, the chip is put into a power down mode.
This pin has to be driven from external clock 3.58MHz source.
(carrier detect)(active low) This output indicates the presence of in-band signals at
the device input.
The demodulated FSK data is output to this pin.
