Pin22: 3V3
Pin20: SW DIO
Pin19: SW DCLK
Pin18: RESET
Pin21: GND
Layout Note:
The ENET(RMII) signals must be length-matched by TX and RX groups:
That is, the TX group should be matched within 300 Mil (7.62 mm),
and the RX group should be matched within 300 Mil (7.62 mm).
Total length should not exceed 1750 Mil (44.5 mm).
There is no requirement to match the TX and RX groups because their clocks are not related.
Layout Note:
2. Route the DP and DM signals on the top (or bottom) layer of the board.
The USB interface (USB 2.0):
Layout Note:
1. Route the high-speed clocks and the DP and DM differential pair firstly.
3. The trace width and spacing of the DP and DM signals must
meet the differential impedance requirement of 90 Ω.
4. Match the overall differential length difference to less than 5 mils.
5. Keep the DP and DM traces as short as possible.
1. Route all signals at the same length within 100 Mils.
2. The controlled impedance for the single-ended traces must be 50 Ω.
The CSI interface (running at up to 80 MHz):
