The LTC6951IUHF is a low-power, low-phase-noise, low-current integrated programmable frequency synthesisers designed for use in HF-band applications. The device is designed to synthesise frequencies from 1 MHz to 20 MHz with a resolution of 1 kHz. This versatile, feature-rich device allows users to program a wide range of frequencies, Output drive strength, configuration, and logic voltage levels. The LTC6951IUHF has a 600 kHz reference input frequency, which can be selected from an internal oscillator, external crystal, or an input from an external reference oscillator. A low jitter 3-digit 7-segment display is also included to display the programmed frequency, enabling the user to quickly identify the programmed output frequency.

The LTC6951IUHF is a highly integrated programmable oscillator and frequency synthesiser that provides frequency switching and tuning capabilities. It also features low harmonic distortion and low additive phase noise. The frequency range can be programmed between 16kHz and 20MHz. The device includes features such as an internal voltage-controlled oscillator (VCO), a programmable divider and clock source, an adjustable current source, and a low-noise prescaler. It allows users to select the desired mode (fixed or variable) and set the required output frequency and amplitude.

The device is built using advanced Silicon-on-Insulator (SOI) CMOS technology and is designed for use in modern high-speed data communication protocols. It provides low jitter, low additive jitter, low power consumption and wide programming capability. The device also provides high reliability, low propagation delay and superior EMI/RFI immunity. The device has a low power consumption of 20 µA from +3.3V, and a maximum output current of 200mA.

The LTC6951IUHF has a wide range of application field and can be used in RF transmitters and receivers, radio communications, broadcast radio stations, land mobile radio (LMR), military communications and satellite communications. In addition, it is also an ideal solution for cellular infrastructure, base stations, point-to-point microwave links and many other applications.

The operation of the LTC6951IUHF is quite simple. It works by starting with a reference input frequency which is then modified and amplified by the programmable divider and clock source. The amplified frequency is then sent to the VCO which is then further divided and amplified to provide the desired output frequency. This output frequency is then sent to the desired output. All adjustments to the frequency, output drive strength and configuration are done using external signals. The internal logic voltages, current sources, and reference signals can also be adjusted according to the user’s needs.

In conclusion, the LTC6951IUHF is an ideal solution for frequency synthesisers, with its low-power, low-phase-noise, low-current and low-harmonic-distortion design. It offers wide range frequency programmed, Output drive strength, configuration, and logic voltage levels. Its easy to program and integrated components makes it a great option for applications that requires cost-effective and reliable frequency synthesiser design.
