Dear Forum members,


1. Traditional way to generate clocks is to use quartz crystal and connect it between two invertors (7404)with
feed back capacitors(0.1uf). (Standard circuit). Is there any alternate better circuit available.

2. For frequency of 12 MHz I use 0.1 uf capacitors. For 32.768KHz circuit what value of capacitors I must use.

3. Are the direct crystal oscillators available. Where in it has four pins two for DC supply two pins to give direct clock
frequency?. If they are available are they available in standard values (32.786 KHz, 11.0592MHz, 6 MHz, 12 MHZ) and where can
I get it (in India).
