Application field of the PI6C2501WE

The PI6C2501WE is an ideal solution for FPGA applications where increased clock frequency and flexibility are required. It can be used to generate multiple independent clock outputs, including differential LVPECL, LVDS, SSTL, CML and CMOS capable of operating up to 1.2 GHz. The PI6C2501WE also offers the ability to meet the stringent jitter requirements of many FPGAs.

The PI6C2501WE can be used in a wide range of different applications, including vehicle infotainment systems, digital video recorders and digital signage. It is also suitable for use in the digital media, medical, broadcasting and networking fields. In addition to FPGA applications, the PI6C2501WE can also be used in any system that requires a high-speed, high-frequency clock.

Working principle of the PI6C2501WE

The PI6C2501WE is based on an innovative PLL design that combines a ring oscillator, voltage-controlled oscillator (VCO), signal detector and a variable reference divider to generate a broad range of frequencies. This device includes two different PLLs, one for the reference signal and the other for the output frequency. The reference PLL functions as a frequency multiplier to generate the output frequency. The variable reference divider allows the user to adjust the reference signal frequency and the frequency multiplier to create a wide variety of output frequencies. Additionally, the PLLs are voltage-controlled which allows the user to adjust the frequency of the output signal while keeping the output signal’s frequency within a given tolerance.

The PI6C2501WE also features a differential voltage-controlled oscillator (VCO) with an integrated differential amplifier. The VCO operates within a frequency range of 600MHz to 1.2GHz and can be programmed with various output frequency settings. The PI6C2501WE contains a programmable reference divider which is used to accurately divide the reference frequency to create the desired output frequency. Additionally, a signal detector is included to detect changes in the output frequency and send feedback to the PLL to adjust the reference divider. This ensures that the output frequency remains within tolerance and eliminates the need for external clock trimming.

Conclusion

The PI6C2501WE is a versatile, high-performance frequency synthesizer, clock generator and timing device. It is designed for FPGA applications and can be used to generate a wide variety of output frequencies. The device features an innovative PLL design with a variable reference divider and voltage-controlled oscillator for maximum flexibility. In addition, the device includes a signal detector to ensure that the output frequency remains within tolerance. This device is ideal for any application that requires a high-speed, high-frequency clock.
