JAJSG25B August 2018 – April 2020 AMC1035
PRODUCTION DATA.
The AMC1035 offers the IEEE 802.3-compliant Manchester coding feature that generates at least one transition per bit to support clock signal recovery from the bitstream. The Manchester coding combines the clock and data information using exclusive-OR (XOR) logical operation that results in a bitstream free of DC components. Figure 42 shows the resulting bitstream from this coding. The duty cycle of the Manchester encoded bitstream depends on the duty cycle of the input clock CLKIN. To enable Manchester coding on the AMC1035, pull the input pin MCE high. The DOUT signal is inverted if the MCE status changes when CLKIN is high.
