Note 1:
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.
Functional Description
The SKY13417-485LF includes an internal negative voltage
generator and decoder that eliminate the need for external DC
blocking capacitors on the RF ports. No external components are
required for proper operation. DC decoupling capacitors may be
added on the VDD and control lines if necessary.
Switching is controlled by three control voltage inputs, V1, V2, and
V3. Depending on the logic voltage level applied to the control
pins, the antenna pin is connected to one of seven switched RF
outputs or a 50
Ω
termination.
The recommended startup sequence is:
1. Apply VDD
2. Apply V1, V2, and V3 voltages
3. Apply RF input
The device must be turned off in reverse order.
Electrical and Mechanical Specifications
The absolute maximum ratings of the SKY13417-485LF are
provided in Table 2. Electrical specifications are provided in
Table 3.
The state of the SKY13417-485LF is determined by the logic
shown in Table 4.
The isolation matrix shown in Table 5 provides the port-to-port
isolation for all available RF states at three different frequencies:
