ispClock5600 Family Data Sheet
GOE – Global output enable. This pin drives all outputs to a high-impedance state when it is pulled HIGH. GOE
also controls the internal feedback buffer, so that bringing GOE high will cause the PLL to lose lock.
PS0, PS1 – These input pins are used to select one of four user-defined configuration profiles for the device.
PLL_BYPASS – When this pin is pulled LOW, the V-dividers are driven from the output of the device’s VCO, and
the device behaves as a phase-locked loop. When this pin is pulled HIGH, the V-dividers are driven directly from
the output of the M-divider, and the PLL functions are effectively bypassed.
RESET – When this pin is pulled HIGH, all on-board counters are reset, and lock is lost.
TEST1,TEST2 – These pins are used for factory test functions, and should always be tied to ground.
n/c – These pins have no internal connection. We recommend that they be left unconnected.
RESERVED – These pins are reserved for factory use and should be left unconnected.
