5-3-4-2 Electrical Specifications (FaxCentre F12 only)
This section provides the electrical specifications.
DC Characteristics
Table presents the DC characteristics.
IMPORTANT: CLOCK pin timing is measured at TTL levels, not CMOS. The system CLOCK driver must
be configured correctly in order to ensure that duty cycle and Vil specifications are met.
