Programming Description
(Continued)
2.5.3
The OSC
pin can be optimized for operating with an external crystal resonator or an external reference frequency source (i.e.
TCXO). If the application uses an external reference frequency source, the current dissipation of the LMX1600/01/02 can be re-
duced with the Logic Mode (0.5 mA typ.). Crystal Mode should be used when an external crystal resonator is used. Logic Mode
is used when an external reference frequency source is used. In Logic Mode, OSC
OUT
should be connected to a 30 pF capacitor
to ground for optimum performance.
When the FoLD output state is selected to CMOS high/low levels, the OSC Mode is forced to Crystal Mode.

SERIAL DATA INPUT TIMING
Note 17:
Data shifted into register on clock rising edge.
Data is shifted in MSB first.
TEST CONDITIONS:
The Serial Data Input Timing is tested using a symmetrical waveform around V
CC
/2. The test waveform has
an edge rate of 0.6 V/ns with amplitudes of 2.2V
