Zarlink Semiconductor Inc.
J3
tms
I
u
Test Mode Select (LVCMOS).
JTAG signal that controls the state transitions of
the TAP controller. This pin is internally pulled up to V
DD
. If this pin is not used
then it should be left unconnected.
Master Clock
K4
osci
I
Oscillator Master Clock Input (LVCMOS).
This input accepts a 20 MHz
reference from a clock oscillator (TCXO, OCXO). The stability and accuracy of
the clock at this input determines the free-run accuracy and the long term
holdover stability of the output clocks.
K5
osco
O
Oscillator Master Clock Output (LVCMOS).
This pin must be left unconnected
when the osci pin is connected to a clock oscillator.
