HT9032D

lingxingic · Telecom Interface ICs · SOP-8

HT9032D from lingxingic, in a SOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 DOUT output FSK demodulator data output. During normal operation outputs the recovered CID data stream (alternating '0'/'1' marker sequence followed by data); otherwise held high ('1').
2 VDD power_in Internal logic supply. Operating range 3.5 V to 5.5 V (typ 5.0 V). Typical IDD ≈ 3.2 mA active, standby current ≈ 1 µA.
3 TIP input Telephone-line TIP input to the FSK front-end. Internally biased to 1/2 VDD during normal operation; must be DC-isolated (AC coupled) from the telephone line. Differential input impedance ≈ 500 kΩ (TIP,RING).
4 RING input Telephone-line RING input to the FSK front-end. Internally biased to 1/2 VDD during normal operation; must be DC-isolated (AC coupled) from the telephone line.
5 PDWN input Power-down control, Schmitt-trigger input. PDWN = '1' places the circuit in power-saving mode; PDWN = '0' selects normal operation. VIH ≥ 0.8 V, VIL ≤ 0.2·VDD; threshold VT- 2.0-2.6 V, VT+ 2.5-3.0 V at VDD = 5 V.
6 VSS power_in Internal logic ground (0 V reference).
7 X2 output Clock generator oscillator output; the second terminal of the crystal/ceramic resonator. Typical resonator is 3.58 MHz with 10 MΩ feedback and 30 pF load caps.
8 X1 input Clock generator oscillator input; one terminal of the crystal/ceramic resonator, or an external 3.58 MHz clock source injection point.
