SKY13397-388LF Block Diagram Description The SKY13397-388LF is a double-pole, five-throw (DP5T) switch designed for broadband, high-power switching applications that demand low harmonics and low insertion loss. The switch is optimized for 3G WCDMA applications. The SKY13397-388LF features integrated logic that uses only two control lines for switch operation. The low current consumption of the device makes it very suitable for battery-operated applications. The switch is manufactured using a state of the art Silicon on Insulator (SOI) process, and is provided in a compact Quad Flat No-Lead (QFN) 2.3 x 2.3 mm 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. Figure 2.

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 SKY13397-388LF 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 two control voltage inputs, GPIO1 and GPIO2. Depending on the logic voltage level applied to the control pins, the OUT1 signal (pin 4) is connected to one of two switched RF inputs (IN1A or IN1B) through a low insertion loss path, while the OUT2 signal (pin 2) is simultaneously switched to one of three RF inputs (IN2A, IN2B, IN2C). For proper switching operation, the SKY13397-388LF must be set to a state for a minimum of 10 μs before changing to a different state. Shutdown mode is enabled by connecting both control pins to logic low. This mode reduces the overall current consumption of the device to 5 μA, typical. To prevent the switch from accidentally entering shutdown mode during switching, caution must be taken to avoid having both control signals (GPIO1 and GPIO2) set to logic low for more than 500 ns. When exiting shutdown mode, the switch has a 25 μs startup time before switching occurs.
