... NW6003 TYPE II CALLER ID DECODER FUNCTIONAL DESCRIPTION CALLER ID SPECS SUPPORTED The NW6003 is a type II Caller ID device with Call Waiting capability. It supports Bellcore, BT and CCA specifications. The major differences between above specs are as follows (refer to Figure 13, Figure 14, Figure 15, Figure 16 and Figure 17): BELLCORE Bellcore GR-30-CORE and SR-TSV-002476 define the ...

... NW6003 TYPE II CALLER ID DECODER CLIP/CID CALL ARRIVAL DETECTION Figure 6 shows the typical application circuit to detect the CLIP/CID call arrival signals. The diode bridge works for both single ended and balanced ring signals. R1 and R2 are used to set the maximum loading and must be of some value to achieve balanced loading. The ring signal is attenuated by R1, R3 and R4 resistor devider before being applied to pin TRIGIN ...

... NW6003 TYPE II CALLER ID DECODER DUAL TONE ALERT SIGNAL DETECTION BT specifies a Dual Tone Alert Signal in both idle (on-hook) state and loop (off-hook) state, while Bellcore specifies a similar Dual Tone Alert Signal called CPE Alerting Signal (CAS) in off-hook state. The low and high tone frequencies of two different systems are as follows: ...

... Mode ‘1’ In this mode, the microcontroller supplies read pulses (DCLK) to shift the 8-bit data words out of the NW6003, onto the DATA pin. The NW6003 asserts DR to denote the word boundary and indicate to the microprocessor that a new word has become available. Internal to the device, the demodulated data bits are sampled and stored ...

... Figure 10. Applicaiton of Clock Driven Circuit INTERRUPT The NW6003 provides an open drain interrupt output INT to interrupt the microcontroller. Either TRIGOUT low, STD high or DR low will activate the INT and it will remain active ‘low’ until all of these three pins return to an inactive state. The microcontroller should read these pins through input ports to detect the interrupt type (TRIGOUT, STD or DR) and to make the correspondent response ...

... NW6003 TYPE II CALLER ID DECODER APPLICATION INFORMATION APPLICATION CIRCUITS Figure 11 shows the typical NW6003 application circuit. For 5 V operation, the gain ratio of the op amp is set to unity to optimize the electrical characteristics. As the power supply voltage drops, the threshold of tone and FSK detectors will be lower. To meet the BT and Bellcore tone reject level requirements, the gain of the op amp should be adjusted according to the graph in Figure 12 ...
