Data pin. When this bit is set, modulation data samples are to
be presented on the Mod_in pin.
Modulation Address Disable = One-bit flag to indicate the
presence of the address as modulation data samples are
presented on either the Mod_in or Data pins. When this bit is
cleared, the address is presented with the modulation data
samples (i.e., all transfers are 16 bits long). When this bit is set,
no address is presented with the modulation data samples (i.e.,
all transfers are 2 to 12 bits long).
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 Fpd_main where they are
passed to the main
Σ modulator at the selected magnitude
offset on the next falling edge of Fpd_main. Modulation Data Register
values are 2's complement format. As shown in Figure 12, the
value to be loaded is:
Modulation Data Bits = Modulation data samples that represent
the 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 SKY72310 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
tape and reel format. For packaging details, refer to the Skyworks
Application Note, Tape and Reel, document number 101568.
Electrical and Mechanical Specifications
Signal pin assignments and functional pin descriptions are
described in Table 4. The absolute maximum ratings of the
SKY72310 are provided in Table 5. The recommended operating
conditions are specified in Table 6 and electrical specifications
are provided in Table 7.
Figure 13 provides a schematic diagram for the SKY72310 using
Skyworks SKY73120 890-960 MHz VCO. Figure 14 provides a
schematic diagram for the SKY72310 using a non-Skyworks VCO.
Figure 15 shows the package dimensions for the 24-pin QFN and
Figure 16 provides the tape and reel dimensions.
Electrostatic Discharge (ESD) Sensitivity
The SKY72310 is a static-sensitive electronic device. Do not
operate or store near strong electrostatic fields. Take proper ESD
precautions.
