Microchip PL133-37TC-R: Low-Jitter LVCMOS Oscillator for Precision Timing Applications
In the realm of modern electronics, the demand for precise and reliable timing signals is paramount. From high-speed data communication and network infrastructure to test and measurement equipment, the integrity of the clock signal directly impacts overall system performance. The Microchip PL133-37TC-R stands out as a critical component engineered to meet these stringent demands, offering a robust solution as a low-jitter LVCMOS oscillator.
This oscillator is designed to provide a stable fundamental-frequency clock source. The PL133-37TC-R operates at 3.3V and delivers a standard LVCMOS output, making it highly compatible with a vast array of digital logic circuits, including FPGAs, ASICs, and microprocessors. Its primary distinguishing feature is its exceptionally low phase jitter, specified at less than 1 ps (typical) when integrated from 12 kHz to 20 MHz. This ultra-low jitter is crucial for applications where timing margins are tight, as it minimizes bit errors in serial data links and improves the accuracy of sampling clocks in data converters.
The device is housed in a compact 5.0mm x 3.2mm ceramic surface-mount package, which is ideal for space-constrained PCB designs. It also boasts a wide operating temperature range of -40°C to +85°C, ensuring reliable performance across industrial environments. Furthermore, the oscillator features exceptional frequency stability of ±25 ppm, guaranteeing that the output frequency remains consistent despite variations in temperature, voltage, or load conditions.
Key applications for the PL133-37TC-R include:
High-Bandwidth Networking Equipment: Where low jitter is essential for maintaining signal integrity in switches, routers, and optical transport networks.
Data Center and Enterprise Storage: Providing precise timing for server motherboards and storage area networks (SANs).
Professional and Broadcast Video: Ensuring clean clock signals for high-resolution video processing and transmission.
Test and Measurement Instruments: Serving as a stable frequency reference for oscilloscopes, signal generators, and spectrum analyzers.
Wireless Infrastructure: Supporting baseband unit (BBU) and remote radio unit (RRU) timing requirements.
The Microchip PL133-37TC-R is a high-performance, low-jitter LVCMOS oscillator that delivers exceptional timing accuracy and reliability. Its combination of ultra-low phase jitter, robust construction, and industry-standard packaging makes it an indispensable component for designers tackling the challenges of next-generation precision electronic systems.
