The PL500-16SC is a precision-timing clock generator system developed by Texas Instruments (TI), used for a wide range of digital audio, video, and telecommunications applications. This programmable multi-function frequency synthesizer and clock generator system can generate frequencies from 0.1 MHz to 1000 MHz with an output signal accuracy of + or - 0.3ppm. The portability and high signal accuracy of the PL500-16SC make it ideal for applications in point-to-point and point-to-multipoint radio, monitoring and surveillance systems, industrial, medical and military environments, as well as a range of vehicle and aircraft applications.

The PL500-16SC incorporates a range of sophisticated programming and precision-timing features, including a high-speed programmable frequency synthesizer, a variable-delay clock generator, a variable-width clock comparator and a programmable, adjustable-precision time-delay circuit. It also contains a wide range of programmable parameters, including a frequency selection for the synthesizer, pre-programmed and user-defined widths for the comparator and clock generator, and pre-programmed and user-defined fixed and adjustable precision time delays. Together, these features allow the PL500-16SC to provide fast, accurate programmable signal source and timing solutions for a variety of digital audio, visual and telecommunications systems.

The working principle of the PL500-16SC is based on intuitive digital technology. The frequency information is programmed using a hand-held programmer such as the TI-1218 or the TI-1363, which provides the programming data to the chip via a serial SPI interface. The chip then stores the frequency information and generates the appropriate frequency from an oscillator circuit. This frequency is then sent to the central output circuit, where it is compared and adjusted to the target frequency by a precision-timing technique. The precision-timing technique employed by the PL500-16SC allows for frequency accuracy of + or - 0.3ppm over the 0.1 MHz to 1000 MHz frequency range.

The PL500-16SC provides an ideal solution for precision-timing applications in a variety of industries. Its portability and programmability make it a cost-effective and reliable solution for radio, monitoring and surveillance systems, industrial, medical and military applications as well as a range of vehicle and aircraft applications. Its wide frequency range and high signal accuracy also make it an ideal choice for portable applications in digital audio, video and telecommunications.
