I am trying to find a programmable frequency divider chip, but haven't had any luck so far.
This chip should have two inputs, where I will connect 22.5792 MHz and 24.576 MHz crystal oscillators. This chip should also have 4 outputs where the divided forms of the input clocks will be present. For example:
O1 = 22.5792 / 8
O2 = 24.576 / 4
O3 = 24.576 / 2
O4 = 24.576 / 8
There should also be some kind of a control port (SPI or I2C) that I can use to configure the outputs. It is very important that I use crystal oscillators, so a PLL type synthesizes is a no go.
I know that this type of circuit is available as ASIC IP's, but I obviously need an IC that does this. Anybody know a chip that does this?
