The SI5335D-B05187-GMR is a clock generator and phase-locked loop (PLL) frequency synthesizer designed to provide a highly integrated solution for clock and timing applications. It offers leading edge performance, low jitter, low power consumption, and integrated features to minimize board area and system cost. With its on-chip phase-locked loop and frequency synthesizers, the SI5335D-B05187-GMR offers a versatile and cost-effective solution for applications where low EMI, low jitter, and low power are major requirements.

The SI5335D-B05187-GMR is ideal for applications such as Ethernet and Wi-Fi routing, storage, and streaming applications, media servers, set-top boxes, telecommunications, clock fan-out, wireless base stations, and consumer electronics. Additionally, the SI5335D-B05187-GMR is designed to support multiple PLLs, ranging from low-cost consumer applications to high-end telecom applications. It also offers fast phase-lock times and low jitter for use in harsh environments.

The SI5335D-B05187-GMR uses an advanced analog phase-locked loop (PLL), along with a set of digital frequency synthesizers, to generate high-precision clock frequencies from an external reference signal. It is also capable of frequency multiplication and division, with a maximum of 10 output frequencies available from a single oscillator. The SI5335D-B05187-GMR also offers frequency agility, allowing the user to quickly adjust the output frequencies without the need for hardware or firmware changes.

The SI5335D-B05187-GMR contains both an integrated high-speed PLL and a frequency synthesizer, providing users with options to generate or shift a wide range of clock frequencies. The input reference signal can be single-ended or differential, while the output frequencies are generated as either differential or single-ended signals. The device also features a Phase Dead Band parameter, which allows users to limit the amount of noise generated by the output during frequency switching. Additionally, the device supports multiple output signals, including clock square waves, complementary clock pulses, and programmable clock outputs.

The SI5335D-B05187-GMR is available in a tiny 8-pin VQFN package with very low power consumption. It supports multiple selectable input and output channels, allowing greater flexibility for system designers. Along with its programmable PLL and frequency synthesis, the device also offers on-chip voltage regulation, which simplifies power supply design and reduces system cost. The on-chip, low-power state requires just 175nW of power, allowing the device to maintain frequency accuracy and reduce system power consumption even at very low input frequencies.

The SI5335D-B05187-GMR is an ideal solution for applications where low jitter, low-power, and a low EMI are important factors. It offers outstanding performance, with low RMS jitter of 0.22ps, high frequency resolution of up to 12kHz, and excellent frequency stability. Additionally, the device integrates several features such as programmable slew rates and pre-emphasized output, to enable designers to optimize their designs to meet the requirements of each application.
