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

This pin’ s description is the same as that given in
10M Receive Clock.
In 10M Serial mode, the ICS1893 sources the 10RCLK to its
MAC/repeater Interface. The 10RCLK synchronizes the data on
the 10RD0 pin between the ICS1893 and the MAC/repeater.
10M (Serial Interface) Receive Data 0.
This pin’ s description is the same as that given in
Receive Data 1–3.
For the 10M Serial Interface, these pins are a no connect. For

Note: The signal on the 10RCLK pin is conditioned by the
The 10RCLK frequency is 10 MHz.
The ICS1893 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 ICS1893 switches between clock sources during the
period between when 10CRS is being asserted and
10RXDV is being asserted. While the ICS1893 locks onto
the incoming data stream, a clock phase change of up to 360
degrees can occur.
The 10RCLK aligns once per packet.
