MC3361BPG-S16-R from UTC Unisonic Tech, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | OSC | passive | Local oscillator connection (pin 1) for the second-converter oscillator. |
| 2 | OSC | passive | Local oscillator connection (pin 2) for the second-converter oscillator. |
| 3 | MIXER OUTPUT | output | Mixer output through an internal 1.8k resistor, feeding the 10.7MHz to 455kHz second IF; mixer conversion gain is 24 dB typ. |
| 4 | Vcc | power_in | Supply voltage pin, operating range 2.5 to 7.0V with absolute maximum of 10V. |
| 5 | LIMITER INPUT | input | IF amplifier/limiter input through an internal 1.8k resistor, with -3dB limiting at 2.0Vrms typ. |
| 6 | DECOUPLING | passive | IF amplifier decoupling pin (pin 6), connected to an external decoupling capacitor. |
| 7 | DECOUPLING | passive | IF amplifier decoupling pin (pin 7), connected to an external decoupling capacitor. |
| 8 | QUADRATURE INPUT | input | Quadrature detector input where the external quadrature tank (ceramic discriminator) connects for FM demodulation. |
| 9 | AUDIO OUTPUT | output | Recovered audio output from the AF amplifier, 100 to 160 mVrms typ. at VIN=10mV. |
| 10 | FILTER INPUT | input | Inverting input of the filter amplifier that monitors the noise band for squelch. |
| 11 | FILTER OUTPUT | output | Filter amplifier output with 1.5Vdc typ. DC level and 40 to 48 dB gain at 10kHz. |
| 12 | SQUELCH INPUT | input | Input to the squelch trigger with hysteresis (50mV typ.); V12=2V is squelch off and GND is squelch on. |
| 13 | SCAN CONTROL | output | Scan control output, 0.5Vdc max low with mute off and 3.0Vdc min high with mute on. |
| 14 | MUTE | passive | Mute switch terminal, which is about 10 ohm on resistance when low and 10M ohm off resistance when high, with a -0.5 to +5.0 Vpeak rating. |
| 15 | GND | power_in | Ground pin, also the other terminal of the internal mute switch. |
| 16 | RF INPUT | input | RF input to the mixer, with 1.0Vrms maximum at Vcc of 4.0V or more. |
