30.6 TBI Mode Receive Timing
The following specifications are valid when the I/O power supply (VDDIOMAC) is 2.5V or 3.3V, ±5%, per the RGMII v2.0
specification, and the MAC/Media Interface Mode Select bits (see
Register #4,”
VMDS-10105 Revision 4.1
October 2006
The drift rate is the (minimum) time for PMA_RX_CLK to drift from 63.5MHz to 64.5MHz or 60MHz to 59MHz from the PMA_RX_CLK lock value. It is applicable
under all input signal conditions (except during code-group alignment), provided that the receiver clock recovery unit was previously locked to PMA_TX_CLK or to
a valid input signal.
