NOTE:
1. Stresses greater than those listed under ABSOLUTE MAXIMUM
RATINGS may cause permanent damage to the device. This is a
stress rating only and functional operation of the device at these or
any other conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.

Description
REF

Reference Clock Input

IN
Feedback Input
TEST (1)
IN
When MID or HIGH, disables PLL (except for conditions of Note 1). REF goes to all outputs. Set LOW for normal operation.
GND/
sOE (1)
IN
Synchronous Output Enable. When HIGH, it stops clock outputs (Except Q2 and Q3) in a LOW state - Q2 and Q3 may be used as
the feedback signal to maintain phase lock. Set GND/
sOE LOW for normal operation.
VDDQ/PE
IN
Selectable positive or negative edge control. When LOW/HIGH the outputs are synchronized with the negative/positive edge of the
reference clock.
FS (2)
IN
Frequency range select. 3 level input.
FS = GND: 25 to 35MHz.
FS = MID (or open): 35 to 60MHz
FS = VDD: 60 to 85MHz
Q0 - Q7
OUT
8 clock output
VDDN
PWR
Power supply for output buffers
VDDQ
PWR
Power supply for phase locked loop and other internal circuitry
GND
PWR
Ground
NOTES:
1. When TEST = MID and GND/
sOE = HIGH, PLL remains active.
2. This input is wired to VDD, GND, or unconnected. Default is MID level. If it is switched in the real time mode, the outputs may glitch, and the PLL
may require an additional lock time before all data sheet limits are achieved.
