Figure 16. Enabling ClockLock & ClockBoost in the Same Design
To use both the ClockLock and ClockBoost circuits in the same design,
designers must use Revision C EPF10K100GC503-3DX devices and the
MAX+PLUS II software, version 7.2 or higher. The revision is identified
by the first digit of the date code stamped on top of the device (e.g., date
code C9715 identifies a Revision C device).

Output
Configuration
This section discusses PCI clamping diodes, slew-rate control, open-drain
output option, and MultiVolt I/O interface for the FLEX 10K devices.
PCI Clamping Diodes
FLEX 10KE (including EPF10K100B) devices have a pull-up clamping
diode on every I/O, dedicated input, and dedicated clock pin. PCI
clamping diodes clamp the signal to the V
CCIO
value and are required for
3.3-V PCI compliance. Clamping diodes can also be used to limit
overshoot in other systems.
Clamping diodes are controlled on a pin-by-pin basis via a logic option in
the MAX+PLUS II software. When V
CCIO
is 3.3 V, a pin which has the
clamping diode turned on can be driven by a 2.5-V or 3.3-V signal, but not
a 5.0-V signal. When V
CCIO
is 2.5 V, a pin which has the clamping diode
turned on can be driven by a 2.5-V signal, but not a 3.3-V or 5.0-V signal.
However, a clamping diode can be turned on for a subset of pins, which
would allow a device to bridge between a 3.3-V PCI bus and a 5.0-V
device.
