The W158HT is mainly used in fields such as data processing, broadcasting, telecommunications and networks. This product can meet the needs of most digital and analog applications, providing superior high performance and reliable long-term operation. In addition, it also provides multiple ways of synchronization and frequency control.

At the core of the W158HT is its timing and frequency control circuitry, which consists of a highly stable, low phase noise, low ripple quartz oscillator, a frequency synthesizer, and a versatile phase locked loop (PLL). This PLL can be used to generate oscillator frequency or multiple reference frequency with low jitter, which is ideal for clock distribution, clock regeneration and frequency multiplication.

The frequency synthesizer technology used in the W158HT is provided by Renesas brand Ku-band PMU, which includes both direct synthesis and programmable frequency division technology. The direct synthesis technology can accurately generate an output frequency from reference frequency, which is determined by a formula programmable in the on-chip RAM. The programmable frequency division technology provides an output clock signal that can be varied following an externally applied clock signal. Both these technologies can be combined to generate a wide range of output frequencies.

The phase locked loop (PLL) architecture used in the W158HT is a type of clock multiplication technique that is commonly used in applications such as clock/data recovery, signal regeneration and timing control. This architecture consists of two components: the phase frequency detector (PFD) and the charge pump (CP). The PFD is responsible for comparing the frequency of the input signal with the frequency of the reference signal. When the two signals are not in phase, the PFD sends a charge pump signal to the CP, which adjusts the frequency of the generated signal in order to lock it in phase with the input signal.

Finally, the W158HT can produce a wide range of onboard references, ranging from crystal oscillators to voltage controlled oscillators (VCOs). The crystal oscillators are highly precise and stable, making them ideal for timing and frequency control tasks. The VCOs produce a stable frequency when supplied with a specific voltage, which can be accurately adjusted using external components.

In conclusion, the W158HT is an effective clock generator and phase locked loop for use in digital and analog applications. It provides a wide range of synchronization and frequency control options, along with a highly stable quartz oscillator and a reliable programmable frequency synthesizer. It is also flexible enough to generate a range of onboard references, making it an ideal choice for applications such as data processing, broadcasting, telecommunications and networks.
