HMC7043LP7FE is a high performance Low Phase Noise Multi-Output Clock Generator that is designed to meet the challenging requirements of small form factor communications and instrumentation systems. The device is capable of producing up to three low noise outputs at frequencies up to 2GHz while achieving extremely low phase noise and high jitter performance. It is ideal for use in applications that require extremely low noise and high precision timing, such as in high performance microwave radio, instrumentation, and narrow bandwidth communication systems.

The HMC7043LP7FE is a well-suited device for applications requiring multiple low-noise output frequencies with low jitter and low phase noise. The device features three low-noise PLLs that can operate from a single input reference frequency, allowing for the generation of multiple high frequency outputs from a single reference clock. Each of the three outputs has its own output enable control, allowing for flexible system design. The device also features selectable dual loop bandwidths and frequency dividers, enabling very low harmonic content and excellent phase noise performance at the output frequencies.

The HMC7043LP7FE is a CMOS device that is capable of operating from a single 2.5 Volts or 3.3 Volt supply voltage. The device offers input and output CMOS compatibility, eliminating the need for any external components to interface with CMOS logic. The device is designed using advanced analog and digital techniques, giving it a highly integrated solution with very low power consumption. The HMC7043LP7FE is available in a variety of package styles, making it a highly flexible and convenient solution for a wide range of applications.

The working principle of HMC7043LP7FE is based on the use of phase-locked loops (PLLs). A PLL is an electronic system that utilizes a phase detector, filter, and oscillator, and loops these components to produce an output frequency that is locked to a reference frequency. The reference frequency is applied to the phase detector, which compares its phase to the output of the VCO and generates a correction signal. This correction signal is input to the VCO and filter, which phase locks the output frequency to the reference frequency. The output of the PLL is then a precise multiplication or division of the reference frequency.

The HMC7043LP7FE incorporates three independent low-noise PLL cores in a single integrated circuit. Each of the three PLLs is capable of generating up to two microwave output frequencies from a single reference clock. The device can also be configured for a single reference clock input and four high frequency outputs. The PLLs feature low phase noise and low jitter, making them ideal for applications requiring high frequency clock stability and accuracy.

The HMC7043LP7FE is a highly integrated and cost-effective solution for contemporary applications that require multiple precise low-noise microwave clock signals. Its low phase noise and low jitter outputs make it ideal for high-performance microwave radios, instrumentation, and communication systems. The device is capable of operating from a 2.5V or 3.3V single supply voltage, making it well-suited for low-power applications. The device also features low harmonic content and excellent phase noise performance at the output frequency range, making it a highly attractive device for a wide range of applications.
