10M (Serial Interface) Collision (Detect).
This pin’s description is the same as that given in
10M (Serial Interface) Carrier Sense.

The 10RCLK pin name is the 10M Serial Interface mapping of
the MII RXCLK (Receive Clock) pin name. The ICS1892
sources the 10RCLK to the MAC/repeater. The ICS1892 uses
10RCLK to synchronize the signals on the 10RD and 10RXDV
pins. The following table contrasts the behavior on the 10RCLK
pin when the mode for the ICS1892 is either 10Base-T or
100Base-TX.
Note: The signal on the 10RCLK pin is conditioned by RXTRI.
The10RCLK frequency is 10
MHz.
The ICS1892 generates
10RCLK from the MDI data
stream using a digital PLL.
When the MDI data stream
terminates, the PLL continues
to operate, synchronously
referenced to the last packet
received.
The ICS1892 switches
between clock sources during
the period between when
10CRS is being asserted and
10RXDV is being asserted.
While the ICS1892 locks onto
the incoming data stream, a
clock phase change of up to
360 degrees can occur.
