LMK1C1103PWR from Texas Instruments, in a TSSOP-8. 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 | CLKIN | input | Single-ended clock input with internal 300-kΩ pulldown resistor to GND. |
| 2 | 1G | input | Global output enable; HIGH enables outputs, LOW disables; internal 300-kΩ pulldown to GND. |
| 3 | Y0 | output | LVCMOS clock output. |
| 4 | GND | power_in | Power supply ground. |
| 5 | Y2 | output | LVCMOS clock output. |
| 6 | VDD | power_in | Power supply terminal for 3.3-V, 2.5-V, or 1.8-V operation; connect 0.1-μF capacitor near pin. |
| 7 | NC | unconnected | No connect. |
| 8 | Y1 | output | LVCMOS clock output. |
