Power Supply Pin Wiring: To prevent mutual interference between power supply pins V
(PLL1), V
patterns for these two systems, and also other digital V
supply source.
External Device Connection: When connecting a device such as synchronous DRAM that
requires timing adjustment, since the AC characteristics are based on the connection of a 30 pF
capacitive load to the CKIO output, the total capacitive load of CKIO should be 30 pF or less. If
the total capacitive load of the CKIO output exceeds 30 pF, a device requiring timing adjustment
should be connected directly to CKIO, while in the case of a device without stringent timing
adjustment requirements, the CKIO output should be received by a buffer to allow the total
capacitive load of the CKIO output to be reduced.
