Microchip PL500-16SC-R: A High-Performance Clock Generator for Precision Timing Applications

In the realm of modern electronics, achieving precise and stable timing is a fundamental requirement for system integrity and performance. The Microchip PL500-16SC-R stands out as a premier clock generator solution engineered to meet the stringent demands of high-speed communication, data center infrastructure, and advanced computing applications.

This device is a highly versatile fractional-N Phase-Locked Loop (PLL) based clock generator. Its primary function is to generate a multitude of low-jitter, high-frequency output clocks from a single input reference clock or crystal. This capability is crucial for synchronizing various subsystems within complex electronic equipment, ensuring data is processed and transmitted without error. The PL500-16SC-R supports input frequencies up to 710 MHz and can generate output frequencies up to 1.4 GHz, providing the necessary speed for next-generation hardware.

A key attribute of this component is its exceptionally low phase jitter performance, measured at a remarkable 200 fs typical (12 kHz – 20 MHz). This ultra-low jitter is paramount in applications like 400G Ethernet, optical transport networks (OTN), and high-speed serial interfaces (e.g., PCI Express), where timing inaccuracies can lead to high bit error rates (BER) and significant degradation of signal integrity. By minimizing jitter, the PL500-16SC-R enhances overall system reliability and data throughput.

Furthermore, the device offers outstanding programmability and flexibility. It can be configured via an I²C or SPI interface, allowing designers to customize output frequencies, formats (LVPECL, LVDS, HCSL), and other parameters dynamically to suit different operational modes. This flexibility simplifies inventory management and design scalability across multiple products. Its robust design also ensures high power supply noise rejection, making it resilient in noisy operational environments typical of densely packed circuit boards.

Housed in a compact 5mm x 5mm 32-lead VFQFN package, the PL500-16SC-R delivers this high performance while addressing the need for miniaturization and power efficiency in space-constrained applications.

ICGOOODFIND: The Microchip PL500-16SC-R is an elite clock generator that sets a high bar for performance. Its combination of ultra-low jitter, wide frequency range, and superior programmability makes it an indispensable component for designers aiming to achieve precision timing and maximum data integrity in cutting-edge electronic systems.
