Absolute Maximum Ratings (Above which the useful life may be impaired. For user guidelines only, not tested.)
Note:
Stresses greater than those listed under 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 specication is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods may affect reliability.

OE_32K
Input
Output Enable for 32 kHz oscillator. High enables
output. Low tri-states the output with a 1uA pull
down current. There is no pull-up or pull-down re-
sistor on this logic input.
5
X1_32K
Input
32kHz OSC input with a 1pF on-chip Xtal load
capacitance
6
X2_32K
Output
32kHz OSC input with a 10pF on-chip Xtal load
capacitance
7
VDD32K_OSC
Power
32kHz OSC VDD supply
8
OUT_32K
Outpuy
32 kHz buffer output
9
VDDIO_32K
Power
32 kHz buffer supply
11
PD_26M
Input
Power down for 26MHz oscillator and output. A low
tri-states the 26MHz outputs while providing a 1 uA
pull-down. The logic pin has no internal pull-up or
pull-down resistor.
13
VDDIO_26M
Power
VDD supply of the two 26MHz buffers
14, 15
OUT1_26M,
OUT2_26M
Output
26MHz output
16
PD
Input
Power down. A low puts the entire chip in power
down. There is no internal pull-up or pull-down
resistor
18
VDD26M_OSC
VDD supply of 26MHz OSC
19
X2_25M
Ouput
26MHz OSC output pin
20
X1/TCXO_IN
Input
26MHz OSC output pin. This pin should be AC
driven for TCXO input. Total Cload of 10pF is inte-
grated into the oscillator.
