The LTC6946IUFD-3#TRPBF is a clock generator, phase-lock loop (PLL) and frequency synthesizer integrated circuit, manufactured by Linear Technology Corporation. Its functional capability combines a clock generator, 8 channels of pulse specified phase shift modulation, a mixer core for tailoring output frequencies over a wide range, and a high-resolution, low-jitter clock driver and multiplexer. This variety of features makes the LTC6946IUFD-3#TRPBF ideal for applications such as clock and data radiation systems, processors, and timing and clock distribution.
The LTC6946IUFD-3#TRPBF incorporates a three-stage, high-resolution PLL with a powerful frequency synthesizer. It uses a low-noise voltage-controlled oscillator (VCO) to generate a reference clock signal. A digital reference input can be used to feed in a reference signal that is divided and multiplied to generate the output clock signal. The user has the option of generating different output signals and controlling the operating frequencies in each output channel.
The LTC6946IUFD-3#TRPBF utilizes an advanced mixer core that provides a wide range of mixing capability up to 11 GHz. This core allows the user to precisely control the frequency translation, leading to low-jitter clock outputs and wide bandwidth clock synchronization. The output clock is further enhanced using a high-resolution clock driver, a programmable PLL and multiplexers, resulting in two direct and eight differential outputs.
In addition to its high-performance clock outputs, the LTC6946IUFD-3#TRPBF offers a slew of other powerful features. It is designed to provide excellent power supply noise rejection and is suitable for applications where reliability and stable clock performance are needed. It also provides synchronization mode and reference selection flexibility, allowing the user to program the IC precisely to their application requirements. The IC is further protected with functional safety features such as temperature monitoring, electrical and failure detection, clock gap control and user-programmable startup options.
The LTC6946IUFD-3#TRPBF offers a wealth of clock-generation capabilities for a variety of applications. It can be used as a single-ended or differential clock solution for memory, processor, and timing networks, and can also be used in multi-domain systems for clock distribution with precise timing. Its integrated high-performance PLL, frequency synthesizer, and digital clock outputs make it a great device for automotive and industrial applications. With its highly flexible programming options, the LTC6946IUFD-3#TRPBF is an excellent clock solution for a wide variety of applications.
