RTC Circuit
1. RC delay time should be in the range of 18~25ms
2. It is recommended that this larger capacitor and small resistor value
in order to reduce the likelihood of glitching of RTCRST#
1. The ICH7m requires a length less than 1 inch on each branch ( from crystal's terminal to RTCXn ball)
3VA_RTC
2. Routing the RTC circuit should be kept simple to simplify the trace length measurement and increase accuracy on calculating trace capacitances
20mil 3. On FR-4, a 5-mils trace has approximately 2pF per inch
NEAR RTC CONNECTOR
20mil
D15 R136
D15 R136
4. Trace signal coupling must limited as much as possible by avoiding the routing of adjacent PCI signals close to RTCX1 and RTCX2
