Description

The SKY13477-001A is a Three-Pole, Four-Throw (3P4T) switch.

Switching is controlled by an integrated GPIO interface with four

control pins. Depending on the logic voltage level applied to the

control pins, the following switched outputs are possible:



RF1 port can be connected to the RF6 or RF5 port.



RF2 port can be connected to the RF7 port.

S3173



RF3 port can be connected to the RF4, RF5, RF6, or RF7 port.

No external DC blocking capacitors are required as long as no DC

voltage is applied on any RF path. The internal voltage regulator

allows the V

DD

supply value to be within 2.45 V to 3.00 V. Logic

control is 1.8 V nominal.

The SKY13477-001A is provided in a compact 15-bump,

1.942 x 1.142 x 0.420 mm (maximum) Wafer Level Chip Scale

Package (WLCSP) that meets requirements for board-level

assembly. Bump and Under-Bump Metallization (UBM) diameters

are 200 microns.

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.

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 SKY13477-001A are

provided in Table 2. Electrical specifications are provided in

Table 3.

The state of the SKY13477-001A is determined by the logic

provided in Table 4.

A timing diagram is provided in Figure 3 that shows the status

and sequence of control lines, V

, and the RF signal for power on

and switching time specifications.
