House91320:
dose any one know of an ideally single chip frequency counter ic that outputs and analog spi or 12c signal?

Analog SPI? SPI is digital.

12c? Do you mean I2C? That is digital, too.

And these days you don't need any special ICs any more. Most garden-variety microcontrollers are good enough for counting. If they can't stand the input frequency you want, add one or a few dividers from a fast enough 74<some letters> series. The days of ECL dividers to get to 100 MHz are gone.

The net is full of examples.

Other than what BAW says, frequency?  accuracy?  amplitude?  maximum integration time?

Zero999:
Even a basic 8-bit PIC16F505 has a counter capable of 20MHz.

Sorry I should have put commas. I figured it out I'm going to use a micro thanks.
