Title: About synchronous oscillator
Post by edwintsu on Aug 2^nd, 2007, 6:40pm

Dear all,

Design a oscillator with 1MegHz typical frequency, and external synchronization frequency from 500KHz to 1.5MegHz.

Use PLL, need a big capacitor for LPF. It still need a lot of chip area even using capacitance multiplier.

I want other methods to implement the frequency spec. Please help me. :-[ Thanks!

Best Regards,
Edwin.
