There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times. Electrical and Mechanical Specifications The absolute maximum ratings of the SKY13473–569LF are provided in Table 2. Electrical specifications are provided in Tables 3 through 6. Figure 3 provides the timing diagram for turnon time and switching time. IMD2 and IMD3 test conditions for various frequencies are listed in Tables 7 and 8, respectively. Triple Beat Ratio (TBR) test conditions for bands 2 and 5 are listed in Table 9. Figure 4 illustrates the test setup used to measure intermodulation products. This industry standardized test is used to simulate the WCDMA Band 1 linearity of the antenna switch. A +20 dBm Continuous Wave (CW) signal, fFUND, is sequentially applied to the TRX1 through TRX10 ports, while a –15 dBm CW blocker signal, fBLK, is applied to the ANT port. The resulting 3rd Order Intermodulation Distortion (IMD3), fRX, is measured over all phases of fFUND. The SKY13473–569LF exhibits exceptional performance for all TRXx ports. Table 10 describes the register content and programming read/write sequences. Refer to the MIPI Alliance Specification for RF Front-End Control Interface (RFFE), v1.10 (26 July 2011) for additional information on MIPI programming sequences and MIPI bus specifications. Figures 5 and 6 provide the timing diagrams for register write commands and read commands, respectively. Table 11 provides the Register_0 logic. Table 12 describes the register parameters and bit values.

PRODUCT_ID 001D 01000101 This is a read-only register. However, during the programming of the Unique Slave Identifier (USID), a write command sequence is performed on this register but the value is not changed.

A write to these bits programs the USID. Note 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.

An Evaluation Board schematic diagram is provided in Figure 7. A recommended ESD protection circuit diagram is provided in Figure 8. An assembly drawing for the Evaluation Board is shown in Figure 9. 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 SKY13473–569LF 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, PCB Design and SMT Assembly/Rework Guidelines for MCM-L Packages, document number 101752. Package Dimensions The PCB layout footprint for the SKY13473–569LF is provided in Figure 10. Typical case markings are shown in Figure 11. Package dimensions for the 20-pin QFN are shown in Figure 12, and tape and reel dimensions are provided in Figure 13. 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. 1 2 3 4 5 VDD VIO SDATA SCLK N/C GND DCH1 Header 6 × C1 33 pF C3 33 pF 2 RFC11 VDD 17 VIO N/C 18 SDATA × 19 SCLK 20 1 C2 10 nF GND TRX10 TRX1 TRX9 TRX2 TRX8 TRX3 TRX7 TRX4 3 RFC10 4 RFC9 7 8 GND ANT TRX6 GND GND 6 RFC7 15 RFC1 14 5 RFC8 16 9 TRX5 RFC2 13 12 RFC3 RFC4 11 RFC5 10 RFC6 S3084 Figure 7.
