Hi,
I have a board with a CY8C4248LQI-BL583. Instead of a crystal a MEMS oscillator (Jauch O 24,000000-JSO21 C1 LC-D-2V3-T3-S-D) is used for the high frequency signal. The output from the crystal is connected to the XTAL24I pin. The XTAL24O pin is floating.
How can I disable, or at least minimize the gain, of the amplifier in the ECO circuit?
I could be wrong, but I suspect that the open amplifier circuit is causing the device to behave unreliably at elevated temperatures.

For the psoc4 device, there is an EXTCLK for oscillator input. But it is only for non-BLE application.
For BLE application, you must use the ECO clock. But it doesn't support for oscillator input.
