Skyworks Solutions Inc. 541BAA001036BBGR

Overview

541BAA001036BBGR from Skyworks Solutions is an Ultra Series™ dual-output crystal oscillator (XO) based on 4th-generation DSPLL® technology, delivering two factory-programmed frequencies between 0.2–1500 MHz with <1 ppb resolution and ultra-low 125 fs RMS phase jitter (12 kHz–20 MHz). It supports LVPECL/LVDS/CML/HCSL/CMOS/Dual CMOS outputs, operates from 1.8/2.5/3.3 V, and is packaged in a 3.2×5 mm CLCC. It serves as a precision timing source in high-speed optical networking and FPGA clocking.

For engineers reviewing the 541BAA001036BBGR datasheet, 541BAA001036BBGR pinout, 541BAA001036BBGR application, or 541BAA001036BBGR equivalent, this page provides verified specifications, package details, real-world use cases, and validated alternative options for dual-frequency, low-jitter clock generation in noise-sensitive 100G+ systems.

Technical Context

The 541BAA001036BBGR implements a digital fractional-N DSPLL architecture with integrated DCO, digital phase detector, and loop filter - enabling simultaneous, independent synthesis of two precise output frequencies without external crystals. Its on-chip power supply regulation delivers –80 dBc typical PSNR, rejecting ripple from switched-mode supplies.

It features pin-controlled frequency select (FS) and output enable (OE), both configurable at order time for active-high/low polarity and pin location (Pin 1 or Pin 2). The device is factory-programmed with non-volatile memory (NVM), ensuring 100% electrical test coverage and eliminating post-manufacture configuration.

FAQ

What output frequencies does the 541BAA001036BBGR support?

The 541BAA001036BBGR supports two factory-programmed frequencies ranging from 0.2 MHz to 1500 MHz, with <1 ppb resolution. Supported formats include LVPECL (up to 1500 MHz), LVDS/CML (up to 1500 MHz), HCSL (up to 400 MHz), and CMOS/Dual CMOS (up to 250 MHz). The exact frequencies are defined at order time and stored in on-chip NVM - the 541BAA001036BBGR itself is not field-reprogrammable.

Does the 541BAA001036BBGR require external configuration after soldering?

No. The 541BAA001036BBGR is fully factory-programmed with its dual frequencies, output format, OE/FS pin assignment, and polarity before shipment. No external EEPROM, I²C interface, or configuration pins are needed - it powers up ready to operate. This eliminates boot-time delays and firmware dependencies, making the 541BAA001036BBGR ideal for secure, deterministic timing in mission-critical systems.

What is the thermal performance of the 541BAA001036BBGR in a 3.2×5 mm package?

In its 3.2×5 mm CLCC package, the 541BAA001036BBGR has a thermal resistance of Θ_JA = 55 °C/W (still air) and Ψ_JB = 20 °C/W. Junction temperature remains within spec (<125 °C) under typical 100 mA supply current and 85 °C ambient, provided the PCB includes adequate copper area under the exposed pad (if present) and standard 4-layer routing. Derating is recommended above 70 °C ambient for continuous full-load operation.

How does the 541BAA001036BBGR achieve –80 dBc PSNR?

The 541BAA001036BBGR achieves –80 dBc typical power supply noise rejection via integrated on-die regulation and DSPLL-based clock synthesis that isolates output phase from VDD ripple. Unlike traditional XOs, its digital loop filter and DCO reject noise across 100 kHz–1 MHz bands - confirmed by characterization with 50 mVpp sine-wave ripple injected at VDD. This eliminates need for external LDOs or LC filters in SMPS-powered systems using the 541BAA001036BBGR.

Can the 541BAA001036BBGR drive both LVDS and CMOS loads simultaneously?

No - the 541BAA001036BBGR is configured for one output format at time of manufacture (e.g., LVDS or CMOS, not both). Dual CMOS is supported, but it delivers two CMOS outputs (in-phase or complementary), not mixed-format outputs. To drive LVDS and CMOS loads in the same system, separate devices or level-shifting buffers are required. The 541BAA001036BBGR's output format is fixed and cannot be changed in-circuit.
