MS7332M from Hangzhou Ruimeng Tech, in a MSOP-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 | Ain | input | Positive input of the reverse-control decoder comparator. Receives the analog signal from which the up-the-coax (reverse) control data is sliced/decoded against the internal Vref. |
| 2 | NC | unconnected | No connect. Leave floating or tie to ground per PCB practice; no internal function. |
| 3 | Vout | output | Video amplifier output. 6dB gain, rail-to-rail driver capable of driving dual 75Ω video loads (or a single 150Ω load); AC- or DC-coupled to the load. |
| 4 | VCC | power_in | Positive supply input, 2.7V-5V single supply. Typical operating current 25mA (13mA quiescent). Bypass with 0.1µF and 22µF capacitors placed as close as possible to this pin. |
| 5 | Vin | input | Video signal input to the amplifier/filter chain. Accepts DAC output either DC-coupled or AC-coupled; internal diode clamp and bias circuit support AC-coupled sync-tip clamping. |
| 6 | GND | power_in | Ground / negative supply reference. Connect to a large ground plane for best video performance. |
| 7 | Dout | output | Reverse-control decoded digital output. Drives high to (VDD-0.1V) and low to 100mV at I=2mA; propagation delay ≤40ns with RL=5.1kΩ, CL=50pF. |
| 8 | Vref | output | Internal reference voltage output for the reverse-control decoder comparator. Bypass to GND with a 0.1µF capacitor to stabilize the reference and reject external interference. |
