The SI5380A-D-GM is part of the family of clock generation and distribution solutions from Silicon Labs. This multifunction clock/timing device is a versatile and cost-effective source of precise frequency clocks, providing customers with clock frequency flexibility and robust design capabilities. The SI5380A-D-GM is a fully programmable clock generator, providing precise frequency sources with both low jitter and low power consumption. It combines a low-jitter clock generator, PLL, and frequency synthesizer into a single device, allowing for flexible clock configurations to customer-specified frequencies.

The SI5380A-D-GM is a low-jitter, voltage controlled oscillator (VCO) PLL that offers up to eight outputs from a single input. It is designed to generate precise frequencies with low jitter and low power consumption. It is ideal for applications requiring low-noise clocks or a wide frequency range, such as IEEE 1394, DDR2 and DDR3, PCIe, SATA, USB 2.0, and Ethernet. The SI5380A-D-GM offers up to 16 MHz of usable frequency range, making it ideally suited for many applications.

The SI5380A-D-GM features three PLLs, each with its own phase-lock loop (PLL1, PLL2, and PLL3). Each PLL has four outputs, allowing for flexibility when configuring output clock frequencies. The device also offers fanout buffers which divide the clock frequency for use with multiple devices at the same time. Additionally, spread spectrum modulation is available to help reduce EMI in high-noise environments. The SI5380A-D-GM also provides programmable voltage and current ranges for both the PLL and VCO, allowing for optimal performance in any system.

The SI5380A-D-GM offers a variety of frequencies with very low power consumption and jitter performance of around 16 ps. It is designed for use in automotive and other high-temperature environments and is tested up to +105C. The device is available in both a 24-pin package and a 28-pin package.

The SI5380A-D-GM features an integrated low-noise, low-power output buffer that is capable of providing a very low-noise and clean clock signal over a wide frequency range. This buffer can provide a voltage range of 12V to 3.3V and an output current range of 2mA to 8mA. The output buffer is designed to be as low-noise as possible, while also maintaining the highest possible output power and accuracy. Additionally, the SI5380A-D-GM can be used to provide synchronous and asynchronous output frequencies, allowing for the flexibility to meet customer needs.

The SI5380A-D-GM is a powerful and versatile clock generator and distribution device, offering both low jitter and low power consumption. It is ideal for applications such as USB 2.0, Ethernet, and PCIe, as well as many other industrial, automotive and consumer electronics applications. With its integrated low-noise output buffer, programmable voltage and current ranges, and spread spectrum modulation, the SI5380A-D-GM offers a robust and reliable source of precise frequency clocks, enabling customers to design innovative systems with greater flexibility and higher performance.
