The DS1086LU-533+T is a versatile clock generator, phase-locked loop (PLL), and frequency synthesizer chip designed to generate clock signals for use in a variety of applications. The device is a 4-input, 3-output PLL intended for frequency multiplication of a 0.5 to 2.5 MHz master crystal oscillator. It has a frequency response of up to 0.5 to 20 MHz with a typical output noise of 30ps rms.

The clock generator, PLL, and frequency synthesizer in the DS1086LU-533+T are all combined on one chip and improve the clocking performance in digital applications. The device uses standard CMOS technology to provide high performance and low power consumption in a small package size.

The main application field of the DS1086LU-533+T includes digital communications, digital broadcast, digital audio, automotive multimedia, CPU and peripheral clocking, telecommunications, wireline and wireless networking, industrial automation, server and storage, and HDTV.

The working principle of DS1086LU-533+T is based on a patented PLL circuit. The PLL consists of a programmable frequency divider, a pair of VCOs (Voltage Controlled Oscillators), and a phase-frequency detector (PFD). The Dividers are used to produce intermediate frequencies which are combined with the main oscillator’s signal in the VCOs to produce the desired output frequency. The PFD compares the incoming signal with the output of the VCOs and produces a signal that is used to adjust the VCOs to keep the two signals in phase. The dividers can be programmed via a serial interface to generate any frequency up to the device’s maximum frequency accuracy.
