Using HC08GZ16 and Running 1MBps CAN off the PLL

Hi all

We are busy investigating the CAN bus which we are going to try and run at 1Mbps. How accurate is the PLL clock? Are its jitter specifications with in the 1% given in the ODVA spec? I have read on ST forums that it is not recommended to run a high speed CAN bus off the PLL due to jitter problems, does Motorola have the same limitation? Our only other option is then to use a 16/32Mhz crystal and not use the PLL.

Any advice/experience would be greatly appreciated
