LAN transmit clock jitter spec

[jautry]

Is there a spec value for the amount of jitter to be expected on the MAC transmit clock output set to run at 50mhz.  This is for the iMXRT1060 proc.  I could not find it in the electrical specs.

Hi,

The RT1060 datasheet does not provide related Ethernet output Reference clock jitter info.

While, the RT1060 EVK board connects external ENET PHY KSZ8081RNB chip has input clock request: 50MHz with ±50 ppm. The RT1060 EVK board Ethernet feature works robust & stable and related ouput clock quality should match with KSZ8081RNB request.

Thanks for the attention.

best regards,

Mike
