I use a board with 8 ADE9000. IN order to reduce the total chip count I’m thinking on using one oscillator to drive all the clocks
Can this be done? What are the parameters that I should take in to account?
Each ADE9000 Clkin pin has approx 4pf of capacitance. The clock osc you use should be able to drive at a min 32pf of capacitance.
If you use a single spi port the spi pins are 10pf X 8 for sclk ,ssb and mosi. be sure your micro can handle the capacitance.
If you can drive the capacitance you should be fine.
If you want the ADE9000 to be sync'ed you will need to broadcast(pull all the chip selects low) and write a software reset command to all parts at the same time.
