AC/DC PARAMETERS
The following tables describe the AD and DC pa-
rameters of the PSD:

The following are issues concerning the parame-
ters presented:
In the DC specification the supply current is
given for different modes of operation. Before
calculating the total power consumption,
determine the percentage of time that the PSD
is in each mode. Also, the supply power is
considerably different if the Turbo bit is
0.
The AC power component gives the PLD,
EEPROM and SRAM mA/MHz specification.
Figures
36
and
37
show the PLD mA/MHz as
a function of the number of Product Terms
(PT) used.
In the PLD timing parameters, add the
required delay when Turbo bit is
0.'
