CDCM9102: External Crystal Connecting to CDCM9102

Hao Wang14

Part Number: CDCM9102

Hi Team,

The datasheet says that CDCM9102 implements a Colpitts Oscillator, is there any special requirements for external crystal?

For example, can we use TXC_8Z crystal oscillator? If so, does it mean that Pin1 should be connected to GND and Pin3 to XIN?

Thanks and Best Regards!

Hi Hao,

The selected crystal must meet the specifications given in datasheet Table 7.5. The crystal you have selected may have an ESR greater than 50 ohms, but otherwise would be fine. You could check with the vendor on the ESR, or select another crystal.

Kind regards,
Lane
