Functional Description The CAN1628T 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, VC1 and VC2. Depending on the logic voltage level applied to the control pins, the RF1 (RF common) pin is connected to one of three switched RF outputs (RF2, RF3, or RF4) through a low insertion path, while the path between the RF1 pin and the other RF pins is in a high isolation state. Electrical and Mechanical Specifications The absolute maximum ratings of the CAN1628T are provided in Table 2. Electrical specifications are provided in Table 3. The state of the CAN1628T is determined by the logic provided in Table 4. 4 Table 2. CAN1628T Absolute Maximum Ratings (Note 1) Symbol Minimum Maximum Units Supply voltage VDD 2.5 5.0 V Control voltage (Note 2) VCTL 1.30 3.30 V Input power PIN +36 dBm Storage temperature TSTG -40 +125 ℃ Operating temperature TOP -40 +85 ℃ ESD 2000 Electrostatic Discharge: Human Body Model (HBM), Class 2 V Note1: 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. Note 2: Any bias voltage applied to the VC1, VC2 pins may damage the device if there is no bias voltage also present on the VDD pin. Maximum control voltage cannot exceed VDD. 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. 5 Table 3.
