DATA SHEET • SKY72302-21 FREQUENCY SYNTHESIZER
Table 4. Multiplexer Output
The Modulation Data Register is used to load the modulation data
samples to the modulation unit. These values are transferred to
the modulation unit on the falling edge of F
passed to the main
offset on the next falling edge of F
values are 2's complement format. As shown in Figure 15, the
value to be loaded is:
14
Modulation Data Bits = Modulation data samples that represent
the desired instantaneous frequency offset to the selected main
synthesizer frequency (selected channel) before being affected
by the modulation data magnitude offset.

Package and Handling Information
Since the device package is sensitive to moisture absorption, it is
baked and vacuum packed before shipping. Instructions on the
shipping container label regarding exposure to moisture after the
container seal is broken must be followed. Otherwise, problems
related to moisture absorption may occur when the part is
subjected to high temperature during solder assembly.
The SKY72302-21 is rated to Moisture Sensitivity Level 3 (MSL3)
at 260 C. It can be used for lead or lead-free soldering.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
