CY26114KZC is a precision clock generator primarily designed for communications applications such as telecom systems, local area networks, Ethernet, and other data applications. Before we discuss its application field and working principle, we should first become familiar with its features.

Features of CY26114KZC

The CY26114KZC is a low-power, precision clock generator, powered by a 3.3V single supply that combines PLL, VCO and crystal reference clock in a single package. It supports spread-spectrum clocking, supports multiple output clock frequencies, is pin-compatible with competitor devices to provide quick design replacement, and is integrated with a slew of control and status registers, as well as an SPI/parallel digital control interface.

The CY26114KZC provides 6 bank outputs with configurable frequencies ranging from 300kHz to 600MHz and supports individual programmable output levels, polarity and slew rate through multiple control and status registers. It also features a built-in voltage controlled oscillator (VCO) and a built-in reference clock to minimize system external components. It supports multiple spread-spectrum frequencies for EMI reduction.

CY26114KZC Application Field

The CY26114KZC is used in a variety of telecommunications and data applications, such as telecom systems, local area networks, and Ethernet. It also applies to FPGA systems, ASICs, data transmission, switch fabric, network processors, data acquisition systems, high speed processor boards, digital video applications, and so on.

CY26114KZC Working Principle

The CY26114KZC combines the phase-locked loop (PLL), voltage controlled oscillator (VCO) and crystal oscillator to generate the clock frequency. The internal clock reference is a quartz crystal oscillator. The internal VCO is connected to the reference clock via the PLL and is adjusted to generate any multiple or fractional frequency that is in range of the VCO and reference clock.

The PLL can transmit the clock reference frequency and VCO frequency to the output. The CY26114KZC has two PLLs and five VCOs, with the VCO frequency from 600MHz to 1000MHz, which can be used to generate various spread-spectrum clock. The output clock frequencies and design details are controlled by an onboard SPI/Parallel digital control interface, which can be used to control the overall system frequency, spread, and any other parameters as needed.

Conclusion

In conclusion, the Cypress CY26114KZC is a precision clock generator that is primarily used in communications applications such as telecom systems, local area networks, Ethernet, and other data applications. It has numerous features such as low-power operation, spread-spectrum support, multiple output clock frequencies, and a digital control interface. It utilizes a PLL, a VCO, and a reference clock to generate the clock frequency.
