Skyworks Solutions Inc. 511FBA100M000BAG

Overview

511FBA100M000BAG from Skyworks Solutions is a factory-programmed, low-jitter crystal oscillator (XO) delivering 100.000 MHz output with ±30 ppm total stability (including 10-year aging), 3.3 V supply, LVDS output format, and –40°C to +85°C operation in a 5 mm × 7 mm 6-pin surface-mount package. It serves as a precision clock source for high-speed serial interfaces requiring deterministic timing.

For engineers reviewing the 511FBA100M000BAG datasheet, 511FBA100M000BAG pinout, 511FBA100M000BAG application, or 511FBA100M000BAG equivalent, this device supports critical timing requirements in PCIe, Gigabit Ethernet, and FPGA clocking where jitter <2.1 ps RMS (LVDS) and supply noise rejection are essential design constraints.

Technical Context

The 511FBA100M000BAG implements Skyworks' DSPLL® synthesis architecture using a fixed-crystal reference and digital frequency synthesis to generate its exact 100.000 MHz LVDS output-eliminating crystal variability across frequencies. Its on-chip LDO regulator filters supply noise, enabling stable operation in electrically noisy environments.

This Si511 variant features OE on Pin 1 (active-high internal pull-up), complementary LVDS outputs (CLK+/CLK−), and full production test coverage including crystal ESR and DLD validation. It operates across the full industrial temperature range with startup time ≤10 ms and disable/enable times of ≤5 µs / ≤20 µs (≥10 MHz).

FAQ

What output format and supply voltage does the 511FBA100M000BAG use?

The 511FBA100M000BAG is configured for LVDS output and 3.3 V supply, as indicated by the "FB" in its part number (F = 3.3 V, B = LVDS). It draws 19–23 mA when enabled and supports differential 100 Ω termination. The device includes an on-chip LDO to maintain output jitter performance despite supply noise.

Does the 511FBA100M000BAG support output enable functionality, and how is it implemented?

Yes, the 511FBA100M000BAG supports active-high output enable (OE) on Pin 1, with an internal pull-up resistor (45 kΩ typical). When OE is low, the LVDS outputs enter high-impedance state with ≤18 mA supply current. Runt suppression ensures no invalid clock edges occur during power-up or OE transitions-critical for FPGA configuration reliability.

What is the total frequency stability specification for the 511FBA100M000BAG, and what does it include?

The 511FBA100M000BAG has ±30 ppm total stability (Grade C), which includes initial calibration accuracy, temperature variation (–20 to +20 ppm), supply voltage change, load variation, mechanical shock/vibration, and 10-year aging at 40°C. This comprehensive spec eliminates need for system-level recalibration over product lifetime.

How does the DSPLL® architecture in the 511FBA100M000BAG improve reliability versus traditional XOs?

The 511FBA100M000BAG uses DSPLL® to synthesize 100.000 MHz from a single fixed-frequency crystal, avoiding the mechanical stress and ESR sensitivity of frequency-tuned crystals. Each unit undergoes production testing for crystal ESR and DLD (drive level dependency), ensuring consistent aging behavior and eliminating early-life failures common in conventional oscillators.

Is the 511FBA100M000BAG pin-compatible with other Si510/511 variants, and what package does it use?

Yes, the 511FBA100M000BAG uses the standard 5 mm × 7 mm, 6-pin surface-mount package (same outline as Figures 6 and 8 in Skyworks Rev. 1.4). It shares mechanical compatibility with all Si510/511 6-pin variants, though OE is on Pin 1 (Si511) versus Pin 2 (Si510)-requiring attention during schematic capture and layout.
