• Manufacturer: Integrated Device Technology

NW6003 TYPE II CALLER ID DECODER
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, NW6003 may be enabled only after the end of ringing to conserve power.
3) The microcontroller in the CPE powers down the NW6003 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) FSKEN may be set always high while the CPE is on-hook. To prevent the FSK demodulator from reacting to other inband signals such as speech, CAS or DTMT tones. The designer may choose
to set FSKEN low during the period that FSK signal is not expected.
