3 / 24 page sames SA2531 A/B/C/E/G/U 3/24 Pin# Symbol Function 25 CS Current Shunt Control Output This N-channel open drain output controls the external high power shunt transistor for the modulation of the line voltage and for shorting the line during make period of pulse dialling. 4V DD Positive Voltage Supply This is the supply pin for the circuit. 26 V SS Negative Power Supply 8MO Melody Output Pulse Density Modulated output of the melody generator for tone ringer. At high impedance when not active. 21 FCI Frequency Comparator Input This is a Schmitt trigger input for ring frequency discrimination. Disabled during off-hook. 10 HS/DP Hook Switch Input and Dial Pulse Output This is an I/O that is pulled high by the hook switch when off- hook. An open drain pulls it low during break periods of pulse dialling and flash. 11 OSC Oscillator Input Oscillator pin for Xtal or ceramic resonator (3.58 MHz). Recommended part is the Murata CSA3.5MG312AM. 9 LLC Line Loss Compensation Select pin for the loss compensation. OPEN = None VDD = 45-75mA VDD = 20-50mA 12 RR Repetition Rate Select pin for repetition rate of melody for the Tone rinser. 22 MODE Signalling Mode Select Input Mode pin Function High LD mode, 10pps, M:B = 33:66 (J:20pps) Open MFonly Low LD mode, 10pps, M:B = 40:60 (J:20pps, M:B = 33:66) 20 R1 Keyboard Rows 19 R2 18 R3 17 R4 16 C1 Keyboard Columns 15 C2 14 C3 13 C4 7CI Complex Impedance Input Input pin for the capacitor in the complex impedance |
