Exposure to maximum rating conditions for extended periods may reduce device reliability. 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 turn-
on 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, f
FUND
, is sequentially
applied to the TRX1 through TRX10 ports, while a –15 dBm CW
blocker signal, f
BLK
, is applied to the ANT port.
The resulting 3
rd
Order Intermodulation Distortion (IMD3), f
RX
, is
measured over all phases of f
FUND
. 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
