Notes:
• Match all signals within 0.25”, including all NAND_IO signals.
• Keep NAND_WE_N and NAND_RE_N signal min 2X spacing (> 16 mils) from the other nets.
• All traces impedance required to be 55 Ω+/- 10%.
• All signals should be referenced to ground. Reference to unbroken power plane is also accepted.
