RF Buffers and Synthesizers
In wireless communication systems, RF buffers and synthesizers are key components to ensure signal integrity and frequency stability.

RF buffers are key components in the signal distribution network, and their main function is to isolate the signal source from the load, preventing changes in the load from affecting the stability of the signal source.Renesas' RF buffer products have the following technical features:
Ultra-low phase noise: Advanced semiconductor process and circuit design techniques are used to achieve extremely low phase noise performance, with typical values up to -160dBc/Hz@1kHz offset, to meet the stringent requirements of high-precision communication systems.
Wide frequency range: supports a wide frequency range from kHz to GHz, which can be adapted to a variety of wireless communication standards and application scenarios.
High Output Driving Capability: With powerful output driving capability, it can directly drive multiple loads and reduce system complexity.
Low-power design: Innovative power management technology is adopted to achieve low-power operation while maintaining high performance, especially suitable for portable and battery-powered devices.

RF synthesizers are the core frequency generation devices in modern communication systems, and Renesas' RF synthesizer product family offers the following outstanding advantages:
Ultra-low phase noise: Patented phase-locked loop (PLL) technology enables ultra-low phase noise to meet the stringent requirements of high-performance test instruments, satellites, radar and 5G wireless systems.
Fast lock-on time: Optimised PLL architecture enables nanosecond frequency switching speeds, particularly suitable for frequency hopping communications and fast channel switching applications.
Wide Frequency Coverage: Supports a wide frequency range from MHz to GHz, and a single device can cover multiple frequency bands, reducing system BOM costs.
High Integration: Integrates key components such as VCO, frequency dividers, loop filters, etc., simplifying system design and saving PCB space.

Radio Synchroniser Technology
In modern communication and networking systems, radio synchronisers are a key technology for achieving precise time synchronisation between devices.Renesas radio synchroniser solutions provide guaranteed high-precision time synchronisation for 5G networks, Industrial Internet of Things (IIoT) and distributed systems.

Renesas' radio synchroniser technology is based on advanced clock synchronisation algorithms and hardware design, with key features including:
Nanosecond Synchronisation Accuracy: Using patented timestamp technology and clock compensation algorithms, nanosecond time synchronisation accuracy can be achieved to meet the most stringent industrial automation standards and communication protocol requirements1.
Multi-protocol support: Compatible with a variety of synchronisation protocols such as IEEE 1588v2 (PTP), SyncE, GPS synchronisation, etc., adapting to the needs of different application scenarios.
Strong anti-interference ability: through digital filtering and adaptive algorithms to effectively inhibit network jitter and drift, in the harsh electromagnetic environment can still maintain stable synchronisation performance.
Low-power design: Optimised circuit architecture and power management techniques reduce power consumption, making them particularly suitable for distributed sensor networks and battery-powered devices.

Clock Jitter Attenuator Solutions
Clock jitter attenuators are a key component in modern high-speed digital systems and communications equipment, removing phase noise and jitter from clock signals and improving overall system performance.

Renesas jitter attenuators utilise low jitter external references and control circuitry to remove unwanted noise from one or more input clock signals. Technical features of these products include:
Ultra-low jitter performance: Typical RMS phase jitter as low as 120fs (12kHz-20MHz) meets the stringent requirements of PCIe® Gen 1/2/3/4/5/6 and high-speed communication applications.
Flexible Frequency Conversion: The products include a frequency conversion stage that allows the output frequency to be different from the input frequency. The input and output frequencies can be integer or non-integer ratios, depending on the device selected. Some devices in the family can support multiple such ratios, resulting in multiple independent frequencies and even non-integer relationships between output frequencies.
Innovative reference design: Use a VCXO or simple crystal as a reference. Innovative technology allows the use of fixed-frequency crystals rather than hard-to-find pullable crystal devices, reducing system complexity and cost.
Wide range of signal support: Supports a variety of single-ended and differential signal levels such as LVCMOS, LVPECL, LVDS, HCSL, HSTL, or SSTL, adapting to different system requirements.
