Electronics Forum / Basics / June 2006external clocking signal
Why do some satellite modems require an external clocking signal? (i.e. 10 MHz) On 6/29/06 11:34 AM, in article 1151606061.227695.175190@x69g2000cwx.googlegroups.com, "mike7411@gmail.com" > Why do some satellite modems require an external clocking signal? > (i.e. 10 MHz) Are you certain they "require" it? It would be reasonable that they provide an option for external clock, but unreasonable to require external clock. Don I guess it's not required, but what is the benefit of having an external clocking option? > On 6/29/06 11:34 AM, in article > 1151606061.227695.175190@x69g2000cwx.googlegroups.com, "mike7411@gmail.com" [quoted text clipped - 6 lines] > > Don On 6/29/06 3:58 PM, in article 1151621915.906207.105530@b68g2000cwa.googlegroups.com, "mike7411@gmail.com" > I guess it's not required, but what is the benefit of having an > external clocking option?

Are you sure it is a clock input? Maybe it's an output, giving you a Primary Reference Frequency signal. Don |
