The output buffers have a format that is open collector with an integrated pull-up resistor, similar to CML.
The output buffers can be enabled with CLKOUTx_EN bits. In addition to this, their output power can be individually set with the CLKOUTx_PWR field. However, these fields only control the output buffer, not the internal channel path that drives this buffer, the SYSREF generator, or the SYSREF output. To power down the entire path, disable the CHx_EN bit.
