The CH304G consists of three main blocks: the input stage, the phase-locked loop (PLL), and the output stage. The input stage receives the incoming signal, which is then processed by the PLL to generate a stable, high-frequency output signal. The output stage buffers the signal and provides the necessary drive strength for the load.

Detailed Schematic

The following table provides a detailed schematic of the CH304G:

Pin	Name	Description
1	VCC	Power supply voltage (2.7V to 5.5V)
2	GND	Ground
