... INDUSTRIAL TEMPERATURE RANGE 2002 Integrated Device Technology, Inc. ENHANCED TYPE II CALLER ID DECODER DESCRIPTION The NW6005 device is a single-chip, 3/5 Volt CMOS caller ID with call waiting detection circuit. It can receive signals following Bellcore GR-30-CORE & SR-TSV-002476, BT SIN227 & SIN242, and ETSI ETS 300 788-1/-2 specifications. ...

... NW6005 ENHANCED TYPE II CALLER ID DECODER PIN INFORMATION (CONTINUED) Name Type Pin No. Data Ready or DT-AS Detection Delayed Steering Output. This pin is active low. When FSK demodulation is enabled, this pin is the Data Ready output. In FSK interface mode 0, this pin is unused and reads ‘1’. While mode 1, this pin is normally high and goes low for half a bit time at the end of a word ...

... Tip/Ring DT-AS Detection is enabled. Tip/Ring input (GS1) is selected. DR/STD STD . Tip/Ring DT-AS detection is required for Bellcore MEI and BT on-hook CLIP. When CB0 is high (‘1’): the NW6005 will be powered down. It draws minimal power 0 0 supply current. When CB0 is low (‘0’): for factory testing only. ...

... CPE is on-hook, either the hybrid is non-functional or the signal level is severely attenuated. Thus, an on-hook CPE must be able to detect DT-AS from Tip/Ring. The NW6005 provides two input OP amps via which the device can be connected both to Tip/Ring and to the Hybrid Receive pairs. Both connection can be differential or single-ended. FSK demodulation is implemented only on Tip/Ring, while DT-AS detection can be on either Tip/Ring or Hybrid Receive ...

... NW6005 ENHANCED TYPE II CALLER ID DECODER DUAL TONE ALERT SIGNAL DETECTION The Dual Tone Alert Signal is used only in off-hook signalling in Bellcore system and ETSI system, but in BT system it is used in both on and off-hook signalling. The low and high tone frequencies of three different systems are as follows: BT ± ...

... Figure 9. Typical Application Circuit For Bellcore MEI Compatible Type II Telephone Operation In FSK mode 1, the received byte is stored in an on-chip register. The microcontroller supplies read pulses (DCLK) to shift the register contents serially out of the NW6005, onto the DATA pin. The DR pin is also used to indicate the word boundary. TIP ...

... GA ABS STD rising edge 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 to save power. 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. ...
