The PL602-23SC is a highly integrated, low-cost programmable clock generator designed to generate multiple independent output frequencies from a single crystal or external reference clock frequency. It combines a low jitter, low noise PLL Synthesizer (Phase Locked Loop) and up to five voltage-controlled oscillators (VCXOs) in a single device. The device can be programmed through a DVI-D (Digital Visual Interface) or an external I2C (Inter-Integrated Circuit) bus.

The PL602-23SC is designed to generate baseband video clocks, audio clocks, and communication system clocks from a single reference frequency. Furthermore, with VCXO control, it can provide very accurate clock rates for digital audio converters, digital video encoders and decoders, and communications devices.

The working principle of the PL602-23SC is quite simple. A reference frequency is supplied to the PL602-23SC from an external oscillator, quartz crystal, or other reference source. This reference frequency is multiplied by the PLL and then divided down to the desired output frequencies. The output frequency is programmed by control bits in the I2C or DVI-D port. The VCXO control is used to trim the output frequency to a very precise level. Output frequencies are generated up to 170 MHz with very low jitter.

The PL602-23SC is suitable for a wide range of consumer and industrial applications such as HDTVs, flat panel displays, consumer A/V systems, DVD players and recorders, set top boxes, DVD-ROMs and audio systems.

It is also well suited for medical and industrial applications such as medical monitoring systems, motor control applications, and RF communications.

In summary, the PL602-23SC is an ideal device for a wide range of clock generation applications. Its integrated PLL and VCXO enable it to generate multiple output frequencies from a single crystal or external reference clock. Its low jitter, low noise, and wide frequency range make it suitable for a variety of consumer and industrial applications.
