Notes:
(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 f
parameter specifies how much the incoming clock can differ from the specified frequency
CLKDEV
during device operation. Simulation does not reflect this parameter.
(2)
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 t

operating conditions tables on pages 46, 49, and 52 of this data sheet. The
I
value depends on the switching frequency and the application

logic. This value is calculated based on the amount of current that each LE
typically consumes. The P

load characteristics and switching frequency, can be calculated using the
guidelines given in Application Note 74 (Evaluating Power for Altera Devices).

Compared to the rest of the device, the embedded array
consumes a negligible amount of power. Therefore, the
embedded array can be ignored when calculating supply
current.
