NW6006 ENHANCED TYPE II CALLER ID DECODER
WITH STUTTER DIAL TONE DETECTOR
Notes:
1) A= 2 sec typ., B= 250 - 500 ms, C= 250 ms, D= 150ms, E depends on data length, Max C+D+E = 2.9 - 3.7 sec, F 200 ms.
2) In a battery operated CPE, NW6006 may be enabled only after the end of ringing to conserve power.
3) The microcontroller in the CPE powers down the NW6006 after CD goes inactive.
4) The microcontroller times out if CD is not activated on the 2nd ring and puts the device into Power-down mode.
5) FSK may be always enabled while the CPE is on-hook. To prevent the FSK demodulator from reacting to other inband signals such as speech, DT-AS or DTMT tones. The designer may
choose to disable FSKduring the period that FSK signal is not expected.
6) PWDN and FSKEN are internal signals decoded from Control Bits CB2-0.
7) When CB0 is low, both DR and DCLK pins are unused.
