SP10T Switch with MIPI for LTE Diversity  
General Description  
Features  
Excellent insertion loss  
The MXD86A0S is a low loss, high isolation SP10T  
– 0.80
 
dB Insertion Loss at 2.7GHz  
P0.1dB @ 27dBm  
switch for antenna diversity receiving.  
The MXD86A0S is compatible with MIPI control,  
which is a key requirement for many cellular  
transceivers. This part is packaged in a compact  
2.4mm x 2.4mm, 20-pin, QFN package which  
allows for a small solution size with no need for  
external DC blocking capacitors (when no external  
DC is applied to the device ports).  
Multi-Band operation 700MHz to 3000MHz  
RFFE serial control interface  
Compact 2.4mm x 2.4mm in QFN-20  
package  
No DC blocking capacitors required (unless  
external DC is applied to the RF ports)  
Applications  
2G/3G/4G antenna diversity  
Cellular modems and USB Devices

MIPI Read and Write Timing  
MIPI supports the following Command Sequences:  
•
Register Write  
• Register_0 Write  
• Register Read  
Figures 3 and 4 provide the timing diagrams for register write commands and read commands, respectively.  
Figure 5 shows the Register 0 Write Command Sequence. Refer to the MIPI Alliance Specification for RF  
Front-End Control Interface (RFFE), v1.10 (26 July 2011) for additional information on MIPI USID  
programming sequences and MIPI bus specifications.

In the timing figures, SA[3:0] is slave address.
 
A[4:0] is register address.
 
D[7:0] is data. “P” is odd parity  
bit.  
Register 0 Write Command Sequence  
Figure shows the Register 0 Write Command Sequence. The Command Sequence starts with an SSC,  
followed by the Register 0 Write Command Frame containing the Slave address, a logic one, and a seven  
bit word to be written to Register 0. The Command Sequence ends with a Bus Park Cycle.

Note:
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  
Power ON and OFF sequence  
Here is the recommendation about power-on/off sequence in order to avoid damaging the device.  
Power ON  
1) Apply voltage supply – V
DD  
2) Apply logic supply – V
IO  
3) Wait 10μs or greater and then apply
MIPI bus signals
–
SCLK and SDATA  
4) Wait 5μs or greater after
MIPI bus goes idle and then apply the RF Signal  
Power OFF  
1) Remove the RF Signal  
2) Remove MIPI bus
–
SCLK and SDATA  
3) Remove logic supply – V

Note
: VIO can be applied to the device before VDD or removed after VDD.  
It is important to wait 10μs after
VIO &
 
VDD are applied before sending SDATA
 
to ensure correction data transmission.  
The
minimum time between a power up and power down sequence (and vice versa) is ≥ 100
us.
