The device is available in an 8mm x 8mm TQFN package with an easy-to-use 2-wire interface which allows the user to program the desired frequency and other configuration settings. The device also features a programmable spread spectrum oscillator, which enables operation with less electromagnetic interference (EMI) and better radio frequency immunity (RFI). The device is able to adapt to any voltage range from 1.8V to 5.5V, making it highly suitable for a wide variety of applications.

Working Principle

The IDT23S08-1HPGI8 clock generator is a phase locked loop (PLL) integrated frequency synthesizer with a programmable spread spectrum oscillator. It uses an external crystal oscillator operating at a high frequency (normally at 20 MHz). This oscillator is used to establish the reference frequency for the clock generator PLL to produce the output frequency range of 150 kHz to 810MHz. The output is divided by two or four (depending on the frequency range) to produce a frequency reference signal. This reference signal is then compared with the voltage controlled oscillator (VCO) to produce a phase locked loop (PLL) between the reference and VCO.

The operation of the IDT23S08-1HPGI8 is controlled by an internal digital phase lock loop (DPLL) that modifies the frequency of the VCO until it is in lock with the reference signal. The output frequency of the PLL can then be adjusted by changing the feedback loop of the oscillator. This process adjusts the frequency of the VCO and the output frequency to achieve the desired output frequency range. The spread spectrum feature can be enabled or disabled via the two-wire interface. This feature enables operation with less EMI and better RFI immunity. The IDT23S08-1HPGI8 clock generator is designed to work with any voltage range from 1.8V to 5.5V, allowing easy integration into a wide range of applications.

Conclusion

The IDT23S08-1HPGI8 is a programmable clock generator with a wide range of applications. It is capable of operating from 150 kHz to 810 MHz with low jitter and spread spectrum capability. The device is suitable for communication, networking, computer, peripheral and industrial automation as well as Broadcast, Medical, Military and Aerospace applications. The on-board programmable frequency synthesizer, low jitter and spread spectrum oscillator, and 20Mhz standard oscillator make this device highly suitable for a wide variety of applications. The device is also designed to help reduce system components and can be easily integrated directly into a system or board using the 2-wire interface.
