The SI5351A-B03437-GTR is a silicon-based clock generator and PLL (phase-locked loop) synthesizer device designed for configurable frequency generation and jitter attenuation applications. This device combines low power consumption with a wide operating temperature range and space-saving package sizes. The SI5351A-B03437-GTR is designed to be pin-compatible in dual-frequency and single-frequency applications.
Overview of the SI5351A-B03437-GTR
The SI5351A-B03437-GTR is an integrated device that includes a high-efficiency PLL to generate any frequency from a few Hz to several hundred MHz. Using an external voltage-controlled crystal oscillator (VCXO) connected to the VCXO pin, this device is able to generate up to three different output frequencies.
The SI5351A-B03437-GTR is extremely configurable, allowing for a variety of output frequency compositions, output voltages, phase-matched behavior, pulse width modulation (PWM) for jitter attenuation and control of the VCO current. The device also features low-phase noise performance, extremely low power consumption and small package sizes. Furthermore, the SI5351A-B03437-GTR provides programmable pull range control and a high-performance spread-spectrum jitter attenuator.
Application Field
The SI5351A-B03437-GTR is well suited for a variety of applications, including networking switches and routers, transceivers, packet-based voice communication systems, digital radio broadcast receivers, and multichannel modem systems. In addition, the low power consumption, wide operating temperature range, and smaller package form factor make this device suitable for portable applications such as personal digital assistants (PDAs), cellular phones, and other handheld devices.
Working Principle
The core of the SI5351A-B03437-GTR is the PLL. The PLL uses a voltage-controlled oscillator (VCO) to generate the desired output frequency based on the feedback provided by the external VCXO. The external VCXO is connected to the device\'s VCXO pin, and the device uses the feedback from the VCXO to lock the VCO to the desired frequency. The PLL also allows for low-phase noise performance, jitter attenuation and control of the VCO current.
The SI5351A-B03437-GTR also includes a slew-rate control logic circuit. The logic circuit controls the rate at which the output frequency changes. The slew-rate control logic also helps reduce output spurs, maintain low-jitter performance and prevent noise from propagating from the PLL circuitry to the output.
Conclusion
The SI5351A-B03437-GTR is an integrated silicon-based clock generator and PLL (phase-locked loop) synthesizer device designed for configurable frequency generation and jitter attenuation applications. This device is an excellent choice for many applications, such as networking switches and routers, transceivers, packet-based voice communication systems, digital radio broadcast receivers, and multichannel modem systems. With an external voltage-controlled crystal oscillator (VCXO) connected to the VCXO pin, this device is able to generate up to three different output frequencies and offers low-phase noise performance and low power consumption.
