Ulrich you beat me to it, we have been using lately the ICS 512 and 570 for some of our projects. If symmetry is not required 80 MHz and a 74 AC 90 will do, if symmetry is a must the only low cost way I know is 160 MHz and a $ 2 MAX3000A gate array. We actually did a symmetrical divide by 3 and 5. Bert Kehren In a message dated 1/3/2013 4:11:45 A.M. Eastern Standard Time, df...@ulrich-bangert.de writes:
Tom, my 50 cents are: Use a 1 Euro expensive ICS503 in a SOIC package to generate a 160 MHz signal from the 10 MHz without further components needed (except one c on the VCC and one on the input) and then divide by 10. Expect a 50 ps one sigma jitter on the output. You MUST use capacitive coupling with an external oscillator. Easily breadboarded! Have used such a configuration to generate phase locked clock signals for older FPGAs without internal clock generation.
