MC12080DR2G from onsemi, in a SOIC-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 | In | input | Non-inverting RF input for the prescaler. Accepts a sine-wave input from 100 MHz to 1.1 GHz (400 mVpp min below 250 MHz, 100 mVpp min above 250 MHz). AC-coupled through 1000 pF in typical use. |
| 2 | VCC | power_in | Positive supply voltage input, 4.5 to 5.5 Vdc (absolute max 7.0 V). Typical supply current 3.7 mA at 5.0 V. Decouple with 0.1 uF to ground close to the pin. |
| 3 | SW1 | input | Divide-ratio select input 1. H = tied to VCC, L = left open (internal pull-down/default). Combined with SW2 and SW3 to select divide ratio 10/20/40/80 per the function table. |
| 4 | Out | output | Divided-frequency output. Open-emitter style output requiring an external load resistor to ground (e.g. 820 ohm for /10 at 1.1 GHz, up to 6.2 k for /80). Delivers ~1.2 Vpp typical output swing; max output current 10 mA. |
| 5 | GND | power_in | Device ground reference (0 V). |
| 6 | SW2 | input | Divide-ratio select input 2. H = tied to VCC, L = left open. Combined with SW1 and SW3 to select divide ratio 10/20/40/80 per the function table. |
| 7 | SW3 | input | Divide-ratio select input 3. H = tied to VCC, L = left open. Combined with SW1 and SW2 to select divide ratio 10/20/40/80 per the function table. |
| 8 | ~In | input | Inverting/complementary RF input. Typically AC-coupled to ground via 1000 pF for single-ended operation, or driven differentially with pin 1 for balanced RF input. |
