Silly question
Can I use external clock source (RCC_CR HSEBYP=1, HSE=1 ) to drive PLL?2012-09-14 01:30 PM

You should be able to, HSEBYP turns off OSC_OUT The PLL should work fine with a 50/50 duty input at HSE/1 up to 8 MHz, it the duty is rougher consider HSE/2 You want to keep the PLL input in the 4-8 MHz range, so if your external clock is 8-16 MHz use HSE/2
