FLEX 10K Embedded Programmable Logic Device Family Data Sheet
Figure 17. 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
MAX+PLUS II software versions 7.2 or higher. The die revision is
indicated by the third digit of the nine-digit code on the top side of the
device.
This section discusses the peripheral component interconnect (PCI)
pull-up clamping diode option, slew-rate control, open-drain output
option, MultiVolt I/O interface, and power sequencing for FLEX 10K
devices. The PCI pull-up clamping diode, slew-rate control, and
open-drain output options are controlled pin-by-pin via Altera logic
options. The MultiVolt I/O interface is controlled by connecting V
a different voltage than V
software via the Global Project Device Options dialog box (Assign
menu).
PCI Clamping Diodes
The EPF10K10A and EPF10K30A devices have a pull-up clamping diode
on every I/O, dedicated input, and dedicated clock pin. PCI clamping
diodes clamp the transient overshoot caused by reflected waves to the
V
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 Altera software. When V
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
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 allows
devices to bridge between a 3.3-V PCI bus and a 5.0-V device.
