Notes to tables:
(1)
To implement the ClockLock and ClockBoost circuitry with the MAX+PLUS II software, designers must specify the
input frequency. The MAX+PLUS II software tunes the PLL in the ClockLock and ClockBoost circuitry to this
frequency. The fCLKDEV parameter specifies how much the incoming clock can differ from the specified frequency
during device operation. Simulation does not reflect this parameter.
(2)
Twenty-five thousand parts per million (PPM) equates to 2.5% of input clock period.
(3)
During device configuration, the ClockLock and ClockBoost circuitry is configured before the rest of the device. If
the incoming clock is supplied during configuration, the ClockLock and ClockBoost circuitry locks during
configuration because the tLOCK value is less than the time required for configuration.
(4)
The tJITTER specification is measured under long-term observation. The maximum value for tJITTER is 200 ps if
tINCLKSTB is lower than 50 ps.
I/O
Conguration
This section discusses the PCI pull-up clamping diode option, slew-rate
control, open-drain output option, and MultiVolt I/O interface for
ACEX 1K devices. The PCI pull-up clamping diode, slew-rate control, and
open-drain output options are controlled pin-by-pin via MAX+PLUS II
logic options. The MultiVolt I/O interface is controlled by connecting
VCCIO to a different voltage than VCCINT. Its effect can be simulated in the
MAX+PLUS II software via the Global Project Device Options dialog
box (Assign menu).
