The LTC6946IUFD-1#TRPBF is an example of a new family of clock generators and frequency synthesizers. This particular model is specifically designed for applications requiring low power consumption and high frequency accuracy. It is well suited for use in embedded applications and provides an excellent way to generate precise clock frequencies for a wide variety of timing and control circuits.
The primary feature of the LTC6946IUFD-1#TRPBF is its low power consumption. It requires as little as 0.46ÊmA at 3V, making it ideal for portable and battery powered applications. Its high speed and low jitter performance ensure precise target frequencies, which are programmable between 200kHz and 25MHz. Its wide output range of 0.8V to 3V enables compatibility with many logic families.
The LTC6946IUFD-1#TRPBF has a simple and effective internal architecture. It consists of a Phase-Locked-Loop (PLL) with a Multi-Synth divider, a 50% duty cycle, push-pull output driver and an on-chip reference oscillator. In order to provide a low jitter output signal, the PLL loop uses a Charge-Pump method to control its internal voltage-controlled oscillator (VCO). The VCO frequency can be programmed to any frequency between 65MHz and 320MHz. The VCO output signal is divided down to the desired target frequency using the Multi-Synth digital divider. This allows for the generation of frequency multiples of the VCO frequency, up to 200 MHz.
The operation of the LTC6946IUFD-1#TRPBF is controlled by an integrated U3 microcontroller, which manages the various functions of the clock generator. The U3 includes an I2C serial interface, through which programmable parameters such as target frequency, skew, modulation and power control can be changed and configurations monitored. The U3 also provides a SPI bus, which can be used to interface with external memory. This allows for varying target frequencies and other parameters to be stored in the external memory, thereby providing the flexibility of defining target frequencies dynamically.
The LTC6946IUFD-1#TRPBF is an ideal choice for applications requiring precise, low power and low jitter clock generation. In addition to its low power consumption and flexible frequency programming, the clock generator also has a small footprint, making it suitable for space-constrained systems. Furthermore, its on-board microcontroller and digital interface allow for an interesting new range of applications that require precise and dynamic frequency generation. This makes the LTC6946IUFD-1#TRPBF a highly versatile and power efficient choice for many high speed clock generation applications.
