This document describes how to switch to and program the unisersal serial bus (USB) analog phase-locked loop (APLL) on the C5506/C5507/C5509A devices. Example assembly programs for programming and switchING to and from the APLL are also provided in the attached zip file. It is assumed that the reader is familiar with the use and operation of the C5506/C5507/C5509A USB digital phase-locked loop (DPLL) and C55x™ Digital Signal Processor (DSP) IDLE procedures.

These are P-Channel enhancement mode silicon gate power fi eld effect transistors. They are advanced power MOSFETs designed, tested, and guaranteed to withstand a specifi ed level of energy in the breakdown avalanche mode of operation. All of these power MOSFETs are designed for applications such as switchING regulators, switchING converters, motor drivers, relay drivers and drivers for other high-power switchING devices. The high input impedance allows these types to be operated directly from integrated circuits.

Servomotors are available as AC or DC motors. Early servomotors were generally DC motors because the only type of control for large currents was through SCRs for many years. As transistors became capable of controlling larger currents and switchING the large currents at higher frequencies, the AC servomotor became used more often. Early servomotors were specifically designed for servo amplifiers. Today a class of motors is designed for applica-tions that may use a servo amplifier or a variable-frequency controller, which means that a motor may be used in a servo system in one application, and used in a variable-frequency drive in another application. Some companies also call any closed-loop system that does not use a stepper motor a servo system, so it is possible for a simple AC induction motor that is connected to a velocity controller to be called a servomotor.

Tiny Planet is small device connected to a GSM cell phone. When the mobile receives a predefined SMS (text message), like "Activate burglar alarm" or "Start backup pump", the circuit automatically recognizes it as a command, and switches the output port accordingly. Besides switchING the port on or off, the user can pulse it for a short period (e.g. 鈥淩eboot remote server鈥?.
