RXCLK 10RCLK 38 Output 10M Receive Clock.
In 10M Serial mode, the ICS1893Y-10 sources the 10RCLK to
its MAC/repeater Interface. The 10RCLK synchronizes the data
on the 10RD0 pin between the ICS1893Y-10 and the
MAC/repeater.
• The 10RCLK frequency is 10 MHz.
• The ICS1893Y-10 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 ICS1893Y-10 switches between clock sources during
the period between when 10CRS is being asserted and
10RXDV is being asserted. While the ICS1893Y-10 locks
onto the incoming data stream, a clock phase change of up
to 360 degrees can occur.
• The 10RCLK aligns once per packet.
