Linear Technology LTC6902IMS Multipurpose Oscillator
The LTC6902IMS is a versatile, precision silicon oscillator manufactured by Linear Technology, designed to provide a wide range of frequency outputs with a high degree of accuracy. This compact, integrated circuit is housed in an MSOP-10 package, making it ideal for applications where space is at a premium. The LTC6902IMS is perfect for a variety of electronic applications, including but not limited to, communications systems, data acquisition systems, and portable battery-powered devices.
One of the key features of the LTC6902IMS is its ability to generate frequencies from 1kHz to 68MHz without the need for any external components such as resistors, capacitors, or inductors. This is achieved through the use of Linear Technology's proprietary silicon oscillator technology, which provides a stable and reliable frequency source.
The oscillator's frequency is easily programmed using a 3-wire SPI-compatible serial interface, which allows for on-the-fly frequency adjustments without the need to power down the system. This makes the LTC6902IMS highly adaptable to dynamic working conditions and able to respond quickly to changing system requirements.
Another significant advantage of the LTC6902IMS is its low power consumption, drawing only 1.7mA of supply current at 2.7V, which is critical for battery-powered and portable applications where preserving power is essential. Additionally, the device has a wide supply voltage range from 2.7V to 5.5V, offering flexibility in various power supply scenarios.
The LTC6902IMS also features a proprietary spread spectrum frequency modulation capability, which can be used to reduce electromagnetic interference (EMI), a common concern in densely packed electronic systems. This can help in meeting stringent EMI and EMC requirements without the need for additional components or shielding.
In summary, the LTC6902IMS from Linear Technology is a high-performance, easy-to-use, and power-efficient solution for generating precise frequencies across a wide range. Its small footprint, programmability, and EMI reduction capabilities make it an excellent choice for designers seeking a reliable and flexible frequency source for their next project.
