1 _{Unlike the complete independence between triggers 0, 1, and 2, and also between the associated trigger masks 0, 1, and 2, respectively, as described in the MIPI RFFE Specification, this}
device uses additional interactions between the provided trigger functions.
The delayed application of updated data to all triggerable registers in this device may be accomplished using any of the three triggers (0, 1, or 2), provided that the particular trigger used is
not currently masked off. If multiple triggers are enabled, any or all of those are sufficient to cause the data to be transferred from shadow registers to destination registers for all triggerable
registers in the device.
It is also necessary to disable all three triggers (i.e., set all three trigger masks) to ensure that data written to any triggerable register will immediately be written to the destination register at
the conclusion of the RFFE command sequence where the data is written.
Evaluation Board Description
The SKYA21054 Evaluation Board is used to test the performance
of the SKYA21054 SP8T Switch. An Evaluation Board schematic
diagram is provided in Figure 6. A recommended ESD protection
circuit diagram is provided in Figure 7. An assembly drawing for
the Evaluation Board is shown in Figure 8.
Package Dimensions
The PCB layout footprint for the SKYA21054 is provided in
Figure 9. Typical part markings are shown in Figure 10. Package
dimensions are shown in Figure 11, and tape and reel dimensions
are provided in Figure 12.
Package and Handling Information
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 SKYA21054 is rated to Moisture Sensitivity Level 1 (MSL1) at
260 C. It can be used for lead or lead-free soldering. For
additional information, refer to the Skyworks Application Note,
Solder Reflow Information, document number 200164.
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.
