LTC6902CMS - Multiphase Oscillator and Spread Spectrum Frequency Modulator

The LTC6902CMS, from Linear Technology, is a versatile, precision silicon oscillator that offers a range of features designed to cater to a multitude of applications requiring signal generation. It is a low-power, self-contained digital frequency source providing a precision-controlled frequency programmable from 1kHz to 68MHz, without the need for any external components.

One of the standout features of the LTC6902CMS is its ability to generate multiple output phases, making it ideal for applications such as clock generation, where phase alignment is crucial. The device can produce up to four different output phases, which are selectable via a simple serial interface.

Additionally, the LTC6902CMS incorporates a spread spectrum frequency modulation (SSFM) capability, which is particularly useful for reducing electromagnetic interference (EMI). By modulating the frequency of the output signal, the energy is spread over a wider bandwidth, thereby lowering the peak spectral energy and helping to meet stringent EMI requirements.

The LTC6902CMS is highly configurable through its serial interface, allowing precise adjustment of the oscillator's frequency, modulation, and phase relationships. This makes it a flexible solution for a variety of complex systems that require fine-tuning of their clock signals.

The device is housed in a compact 10-lead MSOP package, making it suitable for space-constrained applications, while also being robust enough for industrial environments with an operating temperature range from -40°C to 85°C.

Key features of the LTC6902CMS include:

• Programmable frequency range from 1kHz to 68MHz
• Spread spectrum frequency modulation for reduced EMI
• Up to four different output phases available
• Easy configuration via a serial interface
• Low power consumption
• Compact 10-lead MSOP package
• Industrial temperature range: -40°C to 85°C

Whether you're designing a sophisticated communication system, a precision control application, or any other system requiring a reliable and configurable clock source, the LTC6902CMS offers a high-performance solution that simplifies the design process and enhances overall system robustness.
