2 MHz Oscillator and
Clock Selection
Jumper
The Clock Selection Jumper, labeled JP-GCLK, on the CPLD Development/Program-
mer Board is a two-position jumper that allows the users to select which GCLK
dedicated input pin (either GCLK1 or GCLK2) of the ATF15xx should be connected to
the output of the 2 MHz oscillator. In addition, the jumper can be removed to allow an
external clock source to be connected to GCLK1 and/or GCLK2 of the ATF15xx. Figure
2-6 is the circuit diagram of the oscillator and selection jumper. Table 2-14 on page 2-10
shows the pin numbers for the GCLK1 and GCLK2 dedicated input pins of the ATF15xx
in all the different available package types.
Note:
If GCLK1 jumper is set, the jumper will be located toward the side of the board.
On the other hand, if GCLK2 jumper is set, the jumper will be located toward the
middle of the board.
