Hardware

P1P40167 1.8V 4-PLL Low Power Clock Generator by ON Semiconductor (onsemi)

An oscillator provides the reference 27MHz frequency from which 5 clock signals are derived:

• Fixed 22.5792 MHz
• Fixed 27 MHz (= buffered reference clock)
• Fixed 37 MHz (w/ spread spectrum feature)
• Fixed 48 MHz (UCLK?)
• Configurable Audio Clock (22.5792 or 24.576 MHz)

Kermit communicates with Clockgen via I²C.
