Preliminary W91030B

FUNCTIONAL DESCRIPTION

Figure 6 is shown functional blocks of W91030B. The device must operate with a 3.579545 MHz

system clock and consists four major functions and decribed as follows:

Ring Detector

The application circuit in Figure 7-1 illustrates the relationship between the RNGDI, RNGRC and

RNGON signals. The three pin combination is used to detect an increase of the RNGDI voltage from

T+

ground to a level above the Schmitt trigger high going threshold voltage V

C1 = 0.1uF

R1 = 470K

Allowance minimal ring voltage (peak to peak) is:

Tolerance to noise between Tip and Ring and Vss is:

Vpeak (max noise)

Time constant is:

T+(min)

= V

(R1 + R3 + R4) / R4 + 0.7

R5 from 10K ohm to 500K ohm.

Figure 7-1. Application Circuit of the Ring Detecter

The RC time constant of the RNGRC pin is used to delay the output pulse of the RNGON pin for a

T+

low going edge on RNGDI. This edge goes from above the V voltage to the Schmitt trigger low

T-

going threshold voltage V . The RC time constant must be greater than the maximum period of the

ring signal, to ensure a minimum RNGON low interval and to filter the ring signal to get an envelope

output.
