Technical Context

The XUN535100.000000X implements a quartz-crystal-referenced PLL architecture with one-time-programmable (OTP) configuration, enabling precise 100.000000 MHz synthesis without external components. Its LVDS output stage delivers differential swing of 0.25–0.5 V with 45–55% duty cycle at 100 MHz and supports termination into 100 Ω differential loads.

It operates from a single 3.3 V ±5% supply, draws ≤97 mA under LVDS load at 100 MHz, and integrates internal pull-up on E/D (Pin 1) for default-enable operation. The device meets industrial temperature range (-20°C to +70°C) with ±50 ppm total stability including aging, thermal drift, and supply variation.

FAQ

What output type and voltage does XUN535100.000000X support?

XUN535100.000000X is configured for LVDS output and operates from a 3.3 V ±5% supply. Its LVDS interface delivers differential swing of 0.25–0.5 V into 100 Ω loads, with common-mode voltage centered at 1.17–1.375 V. This matches standard LVDS receivers without level-shifting, and the 3.3 V rail aligns with common FPGA and ASIC I/O domains.

What is the frequency stability and operating temperature range of XUN535100.000000X?

XUN535100.000000X guarantees ±50 ppm frequency stability over an operating temperature range of -20°C to +70°C. This specification includes contributions from temperature variation, supply voltage change, load variation, aging, shock, and vibration - ensuring robust timing performance in commercial-extended industrial environments.

Does XUN535100.000000X require external configuration or programming?

No, XUN535100.000000X is factory-programmed with its 100.000000 MHz output and LVDS configuration using one-time programmable (OTP) memory. It requires no external I²C interface, configuration pins, or firmware - enabling plug-and-play deployment with zero setup overhead.

What is the phase jitter performance of XUN535100.000000X, and why does it matter?

XUN535100.000000X delivers 300 fs typical phase jitter integrated from 12 kHz to 20 MHz. This low jitter is critical for high-speed serial links (e.g., PCIe Gen3, 10GbE), where excessive clock noise directly degrades bit error rate (BER) and eye diagram integrity - enabling reliable operation well within industry jitter budgets.

How is the enable/disable function implemented on XUN535100.000000X?

XUN535100.000000X uses Pin 1 (E/D) for output enable/disable control. The pin is pulled high internally, so leaving it open or applying ≥70% VDD enables the LVDS output. Applying ≤30% VDD disables the output, placing OUT and OUT2 in high-impedance state - useful for dynamic power gating and system-level clock control.
