The 342MPLF Frequency Synthesizer is a dual, 4-stage fractional-N PLL frequency synthesizer with an integrated VCO. The device is designed to cover a wide frequency range and provide low phase noise. It is suitable for applications that require low frequency, low jitter and wide locking range. The VCO core is comprised of two bipolar transistors, providing a high-Q, low-noise solution.

The 342MPLF has two independent PLL-synthesizable frequency outputs (F1 and F2), allowing for two independent frequency ranges and phase delays. Output frequency range can be set within 0.2 Hz to 500 MHz. The device supports a wide range of PLL loop bandwidths, from 0.005 to 4MHz. There is also a wide range of options for modulation of frequency: from 1MHz to 100MHz with up to 4x oversampling.

The 342MPLF offers a high degree of flexibility for fractional-N applications. In fractional-N applications, the device offers an integrated VCO, allowing the user to reduce the external component count and improve performance. The 342MPLF includes an integrated, controllable, 4-stage modulator which supports high-resolution (up to 30 bit) ratio division, enabling sub-Hz resolution. In addition, it supports dual-modulus and delay-locked loops with up to 8-bit resolutions, providing accurate frequency switching even in noisy environments.

The device includes an integrated VCO, allowing the user to reduce the external component count and improve performance. The VCO includes a high-Q, low-noise core, allowing the designers to reduce phase noise and maximize frequency stability and accuracy. The 342MPLF also includes a phase-locked loop (PLL) with a wide locking range and proven low phase noise characteristics. This allows the device to provide efficient frequency control over a wide range of inputs and outputs.

The 342MPLF is designed to provide a stable output signal even in noisy environments. The device includes noise cancellation circuitry, which reduces the effect of spurious signals on the output frequency. It also supports a wide range of loop bandwidths, providing the flexibility to adapt to various application needs. Additionally, the device includes an integrated power detector, allowing precise frequency stabilization.

The 342MPLF frequency synthesizer is a powerful device that can be used in a variety of applications. It can be used in radio and communications systems, where low phase noise and wide locking range are essential. Additionally, it can be used in test and measurement equipment, where precise frequency control is needed. Finally, the device can be used in time and frequency sources, where accuracy and stability are critical.
