NW6005 ENHANCED TYPE II CALLER ID DECODER
Notes:
1) A
2) By choosing t
3) AC and DC loads should be removed between 50-150 ms after the end of the FSK signal. The NW6005 may go to power down mode
4) FSKEN should be set low to disable the FSK demodulator, when the FSK signal is not expected.
5) Tip/Ring DT-ASEN, PWDN and FSKEN are internal signals decoded from Control Bits CB2-0.
6) When CB0 is low, both DR and DCLK pins are unused.
