iMX6 32kHz clock output specifications

[emil]

Hello,

Provided that I use SABRE development board for Smart devices with the crystal suggested there, what quality can I expect of the 32kHz output clock in terms of accuracy, phase noise and rise/fall time. I'm outputting the 32kHz clock on the XTALOSC_REF_CLK_32K pin. I cannot find this information in any specification, but maybe I've missed it somewhere?

1) The output clock accuracy will be determined by the accuracy of the crystal used.

2) Unfortunately, we have no data on the phase noise of the output. This is not a parameter that is characterized on this device.

3) The pin on which XTALOSC_REF_CLK_32K is multiplexed is a GPIO-type output buffer. The output rise/fall times for GPIO-type outputs are shown in the datasheet in the section "General Purpose I/O AC Parameters".

Regards,

Clay
