CY29973AIT is a high-performance programmable liming synthesis IC for system clocking. It offers multiple clock generation and synthesis solutions in a wide range of computer, telecom and consumer applications. The device enables users to quickly implement their system’s clock design with a single IC, replacing a variety of legacy discrete devices in the process.

The CY29973AIT includes three PLLs, two clocks and a crystal oscillator. It provides flexibility, high clock frequency accuracy and wide-range frequency outputs with excellent jitter performance. The device is designed to operate in various clock frequencies, such as 12MHz, 25MHz, 50MHz, 100MHz and 200MHz.

The CY29973AIT offers up to fifteen output clocks, programmable in 8K Hz to 200MHz resolution. It also has an integrated jitter attenuator function to achieve ultra-low jitter performance. Additionally, it includes an internal low-noise power supply regulator, which allows an internal power supply design. This reduces time-to-market by providing an efficient and reliable on-chip regulator.

The CY29973AIT uses the PLL architecture to generate various clock frequency output signals. It uses the feedback path to multiply or divide the input reference frequency to attain the desired output frequency. An onboard VCO produces various frequencies, using the reference clock and a wide-band divider to modulate the oscillator.

The CY29973AIT incorporates several features such as programmable USB suspend and clock stopping functions, user-programmable spread-spectrum modulation and adjustable output drive strength to further optimize system clocking performance. In addition, the device offers an integrated power-on reset detect circuit to prevent power failure and provide power supply disruption protection.
