PIN CONFIGURATION
PIN DESCRIPTION
NOTE:
1. When TEST = MID and GND/sOE = HIGH, PLL remains active.
PROGRAMMABLE SKEW
for PCB trace delays, backplane propagation delays or to accommodate
requirements for special timing relationships between clocked compo-
nents. Skew is selectable as a multiple of a time unit t
order of a nanosecond (see PLL Programmable Skew Range and Resolution
Table). There are nine skew configurations available for each output
pair. These configurations are chosen by the nF

Reference Clock Input
Feedback Input
When MID or HIGH, disables PLL (except for conditions of Note 1). REF goes to all outputs. Skew Selections (See Control
Summary Table) remain in effect. Set LOW for normal operation.

Selectable positive or negative edge control. When LOW/HIGH the outputs are synchronized with the negative/positive edge of the
reference clock.
3-level inputs for selecting 1 of 9 skew taps or frequency functions
Selects appropriate oscillator circuit based on anticipated frequency range. (See PLL Programmable Skew Range.)
Three output banks of two outputs with programmable skew (1Q:3Q), and 4Q output has fixed zero skew outputs.

CAPACITANCE
NOTE:
1. Capacitance applies to all inputs except TEST and FS. It is characterized but not
to minimize the number of control pins, 3-level inputs (HIGH-MID-LOW)
are used, they are intended for but not restricted to hard-wiring. Undriven
3-level inputs default to the MID level. Where programmable skew is
not a requirement, the control pins can be left open for the zero skew
default setting. The Control Summary Table shows how to select specific
skew taps by using the nF
