MC12080DR2G

onsemi · Clock Generators, PLLs, Frequency Synthesizers · SOIC-8

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.
