The CY28346OXC from Cypress is a medium-frequency oscillator that can provide precise timing in a variety of applications. It has a wide frequency range from 40kHz to 540kHz and can be used in both single- and dual-frequency modes. The high frequency accuracy and jitter of the device are its key features, as well as its low power consumption and small size. The CY28346OXC is an ideal solution for applications such as clock and data recovery, clock synthesis, and frequency synthesis.

This application-specific oscillator is designed to provide precise frequency control while consuming minimal power. The device features two separate outputs, one which can be configured to generate a fixed or spread-spectrum frequency while the other is used to synthesize an independent frequency. Additionally, the device has a built-in voltage controlled oscillator (VCO) and a fractional-N tuning system, which allows for industrial-grade frequency accuracy and jitter performance.

The CY28346OXC is based on the company’s FLL (flexible-fractional-N-frequency-locked-loop) technology, which uses a PLL-based architecture combined with a voltage-controlled oscillator. This technology allows for high performance, and can be optimized for both spread-spectrum and non-spread-spectrum applications. Additionally, the device provides jitter characteristics that are among the best in the industry.

The CY28346OXC also includes an active cross-over compensation circuit. This allows for an improved VCO performance, and can reduce the number of external components needed to achieve the desired frequency accuracy and jitter performance. Additionally, the active cross-over compensation can be disabled, which reduces the current consumption of the device when it is not in use.

The CY28346OXC is designed to be used in a range of cellular and wireless applications, such as frequency synthesis, clock and data recovery, and frequency generation. The device is well suited for use in GSM, CDMA, and 3G signals. Additionally, the CY28346OXC can be used in multi-tone and spread-spectrum systems such as those found in Bluetooth, Wi-Fi, ZigBee, and other short-range radio-frequency identification (RFID) systems.

A key feature of the CY28346OXC is its flexibility in terms of operating temperature range and power supply voltage. With an operating temperature range of -30°C to +85°C, the device is well suited for serious industrial applications. Additionally, the device can operate from a single-ended supply voltage of 1.65V to 5.5V, and provides a high-performance solution for space-constrained designs.

In conclusion, the CY28346OXC is a medium-frequency oscillator designed to provide precise timing and frequency control in a variety of applications. The device features two separate outputs, a built-in VCO and fractional-N tuning system, and a highly integrated active cross-over compensation circuit. Additionally, the device is designed to provide high performance while consuming minimal power, and is suitable for use in a wide range of industrial applications.
