Skyworks Solutions Inc. 511ABA100M000BAG

Overview

511ABA100M000BAG from Skyworks Solutions is a factory-programmed, 100 MHz CMOS-output silicon oscillator (XO) in a 5 × 7 mm 4-pin package, operating at 3.3 V with ±30 ppm total stability over –40 to +85 °C and supporting low-jitter clock generation for high-speed serial interfaces. It integrates an on-chip LDO regulator for supply noise rejection and features runt suppression on power-up and OE control.

For engineers reviewing the 511ABA100M000BAG datasheet, 511ABA100M000BAG pinout, 511ABA100M000BAG application, or 511ABA100M000BAG equivalent, this part delivers deterministic jitter performance (0.25–0.35 ps RMS phase jitter, 1.875–20 MHz), precise frequency accuracy, and drop-in compatibility with legacy quartz XOs in telecom, FPGA, and Ethernet timing systems.

Technical Context

The 511ABA100M000BAG implements Skyworks' DSPLL® synthesis architecture using a fixed crystal resonator and digital fractional-N PLL to generate 100 MHz output without external loop filters or tuning components. Its internal LDO isolates the oscillator core from supply noise, enabling stable operation in noisy PCB environments.

This Si511-series device uses OE-active-high logic with internal pull-up, supports tristate disable with <5 µs disable time (≥10 MHz), and guarantees startup within 10 ms. It is factory-configured - no field programming required - and conforms to Pb-free, RoHS-compliant manufacturing standards.

FAQ

What output format and voltage does the 511ABA100M000BAG use?

The 511ABA100M000BAG is configured as a 3.3 V CMOS oscillator delivering a single-ended 100.000 MHz square wave. Its output meets standard CMOS logic thresholds (VOH ≥ 0.85×VDD, VOL ≤ 0.15×VDD) and drives up to 15 pF load with 0.45–1.2 ns rise/fall times. This matches common FPGA and ASIC clock input requirements without external level-shifting.

Does the 511ABA100M000BAG require external configuration or programming?

No - the 511ABA100M000BAG is fully factory-programmed with its 100.000 MHz frequency, 3.3 V supply, CMOS output, ±30 ppm stability, OE-active-high polarity, and –40 to +85 °C operating range. It operates immediately upon power-up with no I²C, SPI, or other configuration interface needed, eliminating firmware dependencies and boot-time delays.

How does the 511ABA100M000BAG achieve low jitter in noisy power environments?

The 511ABA100M000BAG integrates an on-chip LDO regulator that isolates the DSPLL core from VDD rail noise. Measured additive jitter due to 100 mVPP supply noise is ≤3.5 ps RMS across 10 kHz–1 MHz, enabling reliable operation directly from switched-mode power supplies without external filtering components.

What is the startup time and enable/disable behavior of the 511ABA100M000BAG?

The 511ABA100M000BAG achieves full-frequency output within 10 ms after VDD reaches minimum specification. With OE active high, the output is enabled by default; pulling OE low disables the output within ≤5 µs (for ≥10 MHz). Runt suppression prevents spurious edges during power-up and OE transitions.

Is the 511ABA100M000BAG pin-compatible with standard 5 × 7 mm quartz oscillators?

Yes - the 511ABA100M000BAG uses the industry-standard 5 × 7 mm, 4-pin SMD footprint with identical pad dimensions and spacing (per IPC-7351). Its Pin 1 (OE), Pin 2 (GND), Pin 3 (CLK), and Pin 4 (VDD) mapping matches common quartz XO layouts, enabling direct replacement without PCB modification.
