Description
The SKY13526-485LF is a single-pole, six-throw (SP6T) antenna
switch with a Mobile Industry Processor Interface (MIPI).
Using advanced switching technologies, the SKY13526-485LF
maintains low insertion loss and high isolation for both transmit
and receive switching paths. The high linearity performance and
low insertion loss achieved by the SKY13526-485LF makes it an
ideal choice for UMTS, CDMA2000, EDGE, and LTE applications.
Depending on the logic applied to the decoder, the antenna pin is
connected to one of six switched RF ports using a low insertion
loss path, while the paths between the antenna pin and the other
RF pins are in a high isolation state. Switching is controlled by the
MIPI decoder. There is an external MIPI select pin that enables
how the switch responds to power mode triggers. When this pin is
grounded, the switch responds to any of the power mode triggers.
When this pin is left open, the switch responds to individual
power mode triggers. No external DC blocking capacitors are
required on the RF paths as long as no DC voltage is applied.
The SKY13526-485LF is manufactured in a compact,
2 x 2 mm, 14-pin surface mount Quad Flat No-Lead (QFN)
package.
A functional block diagram is shown in Figure 1. The pin
configuration and package are shown in Figure 2. Signal pin
assignments and functional pin descriptions are provided in
Table 1.

Table 13. Register Description and Programming (2 of 2)
Register
Name
Address
(Hex)
Parameter
Description
Default
(Binary)
PWR_MODE
Bits[7:6]:
00
00 = Normal operation (active)
01 = Default settings (startup)
10 = Low power (low power)
11 = Reserved
Trigger_Mask_2
Bit[5]:
0
If this bit is set, trigger 2 is disabled. When all triggers are disabled, if
writing to a register that is associated with trigger 2, the data goes
directly to the destination register.
Trigger_Mask_1
Bit[4]:
0
PM_TRIG
(Note 1)
001C
Trigger_Mask_0
If this bit is set, trigger 1 is disabled. When all triggers are disabled, if
writing to a register that is associated with trigger 1, the data goes
directly to the destination register.
Bit[3]:
0
If this bit is set, trigger 0 is disabled. When all triggers are disabled, if
writing to a register that is associated with trigger 0, the data goes
directly to the destination register.
Trigger_2
Bit[2]:
0
If this bit is set, data is loaded into the trigger 2 registers.
Trigger_1
Bit[1]:
0
If this bit is set, data is loaded into the trigger 1 registers
(unsupported).
Trigger_0
Bit[0]:
0
If this bit is set, data is loaded into the trigger 0 registers.
PRODUCT_ID
001D PRODUCT_ID
Bits[7:0]:
11000000
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.
MANUFACTURER_ID 001E MANUFACTURER_ID
Bits[7:0]:
10100101

USID Bits[3:0]:

Programmable USID. 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.
