ECO Load Capacitance Specification
Am having trouble sourcing the 24MHz ECO I have been using in my Production of PSoC4 BLE devices (we've been using the ECS-240-8-36CKM part), so am looking at alternatives.
In the spec document that Cypress have put out for Crystal Oscillator selection and tuning (AN95089), they list a number of key specs for the ECO. One of these is that the load capacitance be 8pF.
Does anyone know how critical that value is? I can find a heap of suitable ECO's, but they all have a load capacitance figure of 10pF. Is that going to totally bugger my RF performance? Or is it something I can tune out easily enough?
