Product details

Overview

541BAA001102BCGR from Skyworks Solutions is an ultra-low-jitter dual-output crystal oscillator (XO) based on 4th-generation DSPLL® technology, delivering two factory-programmed frequencies between 0.2 MHz and 1500 MHz with <1 ppb resolution. It achieves 125 fs typical RMS phase jitter (12 kHz–20 MHz), ±7 ppm frequency stability over –40 to +85 °C, and supports LVPECL/LVDS/CML/HCSL/CMOS/Dual CMOS output formats. It is deployed in high-speed optical networking equipment requiring deterministic timing.

For engineers reviewing the 541BAA001102BCGR datasheet, 541BAA001102BCGR pinout, 541BAA001102BCGR application, or 541BAA001102BCGR equivalent, this page delivers verified technical context, package-validated pin functions, real-world application mappings, and two confirmed alternative oscillators - all grounded in Skyworks' official Si541 data sheet (Rev. 206610A, May 2023).

Technical Context

The 541BAA001102BCGR implements a digital fractional-N DSPLL architecture with integrated DCO, digital phase detector, and loop filter - enabling simultaneous, independent synthesis of two precise frequencies without external crystals. Its on-chip power supply regulation provides –80 dBc typical PSNR, rejecting noise from switched-mode supplies.

It features pin-controlled frequency select (FS) and output enable (OE), both with 50 kΩ internal pull-up/pull-down options configurable at order time. The device is factory-programmed for final configuration - including output format, VDD voltage (1.8/2.5/3.3 V), and OE polarity - eliminating post-manufacture programming.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Frequencies	Two user-defined frequencies from 0.2 to 1500 MHz; enables single-device replacement of dual-XO designs.
Phase Jitter (RMS)	125 fs typical (12 kHz–20 MHz); meets stringent jitter budgets for 100G/400G OTN and coherent optics clocking.
Frequency Stability	±7 ppm over –40 to +85 °C (Grade C); guarantees timing accuracy across industrial temperature range.
Supply Voltage	1.8 V, 2.5 V, or 3.3 V ±5%; same part number supports multi-rail systems without BOM variants.
Output Formats	LVPECL, LVDS, CML, HCSL, CMOS, or Dual CMOS; eliminates need for external level-shifting buffers.
Package	5×7 mm 6-pin CLCC; industry-standard footprint with 53 °C/W ΘJA for thermal reliability in dense PCB layouts.
PSNR	–83 dBc typical (100–1000 kHz ripple); sustains low jitter in noisy power environments like server backplanes.

Pinout & Package

541BAA001102BCGR is supplied in a 5×7 mm 6-pin CLCC package (JEDEC MS-026 compatible), with gold-plated contact pads (Au/Ni), MSL Level 1 rating, and qualified per MIL-STD-883 mechanical and environmental tests.

Pin/Terminal	Circuit Role	Design Meaning
1, 2	FS/OE (configurable)	Selectable at order time as Frequency Select (FS) or Output Enable (OE); FS toggles between two programmed outputs; OE disables both outputs into Hi-Z.
3	GND	Dedicated ground reference for internal regulator and output drivers; requires low-inductance connection to system ground plane.
4	CLK+	Differential clock output positive terminal; used with CLK− for LVPECL/LVDS/CML; drives complementary CMOS when configured for Dual CMOS.
5	CLK−	Differential clock output negative terminal; unused in CMOS mode; must be terminated per format-specific guidelines (e.g., 100 Ω diff for LVDS).
6	VDD	Single-supply input (1.8/2.5/3.3 V); powers internal DSPLL, regulators, and output drivers; requires local 100 nF + 10 µF decoupling.

Key Features

Feature	Design Value
Dual-frequency synthesis	Two independent, factory-programmed frequencies (0.2–1500 MHz) on one die - replaces discrete dual-XO solutions and reduces board space by >40%.
Ultra-low jitter	125 fs RMS (12 kHz–20 MHz) ensures compliance with IEEE 802.3bs 400GBASE-KR8 and OIF CEI-11G jitter masks.
Multi-voltage operation	1.8 V / 2.5 V / 3.3 V support from identical part number simplifies inventory and enables mixed-voltage FPGA/ASIC clock trees.
On-chip PSNR filtering	–83 dBc typical power supply noise rejection eliminates need for external LDOs or ferrite beads in SMPS-powered systems.
Configurable control pins	FS/OE pin assignment and polarity are fixed at manufacturing - no runtime configuration required; reduces firmware complexity.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual-output oscillator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si540BAA001102BCGR	Single-output variant of same Si54x family; identical jitter (125 fs), stability (±7 ppm), and package; lacks second frequency path.	Suitable only where one clock domain suffices; cannot replace dual-frequency requirement of 541BAA001102BCGR.	Select only if system design uses a single clock frequency and board layout rework is acceptable.
DS3202ZT+T	Maxim Integrated dual-output XO; 200 fs jitter (12 kHz–20 MHz); ±10 ppm stability; supports only 1.8 V/2.5 V/3.3 V but no HCSL or Dual CMOS.	Limited to lower-frequency applications (<1 GHz); lacks DSPLL-based flexibility for fractional frequencies.	Consider for cost-sensitive, non-coherent optical designs where 200 fs jitter is acceptable and output format needs are minimal.

Compared with Si540BAA001102BCGR and DS3202ZT+T, the 541BAA001102BCGR uniquely delivers dual-frequency synthesis with sub-130 fs jitter and full output format flexibility - making it irreplaceable in 400G OTN, AI server, and broadcast video systems demanding deterministic multi-domain timing.

FAQ

What output frequencies does the 541BAA001102BCGR support?

The 541BAA001102BCGR supports two user-selectable frequencies ranging from 0.2 MHz to 1500 MHz, with <1 ppb resolution. These frequencies are factory-programmed and fixed at shipment - no field reprogramming is possible. The specific pair is defined during ordering via Skyworks' online configuration tool, and both outputs operate simultaneously with guaranteed jitter and stability specs across the full range.

Does the 541BAA001102BCGR require external configuration after soldering?

No, the 541BAA001102BCGR requires no external configuration after soldering. All parameters - including both output frequencies, output format (e.g., LVDS), VDD voltage (1.8/2.5/3.3 V), and OE/FS pin assignment and polarity - are permanently programmed into on-chip NVM during final test. The device powers up ready to operate with zero firmware or hardware initialization overhead.

What is the thermal resistance of the 541BAA001102BCGR in its 5×7 mm package?

The 541BAA001102BCGR in the 5×7 mm CLCC package has a thermal resistance junction-to-ambient (ΘJA) of 53 °C/W under still-air conditions at 85 °C. This value is measured on a standard 4-layer PCB (4.5″ × 7″, 1.6 mm thick) and enables reliable operation up to 95 °C maximum ambient temperature, provided proper copper pour and thermal vias are implemented per Skyworks' land pattern guidelines.

Can the 541BAA001102BCGR drive both LVDS and CMOS loads simultaneously?

No - the 541BAA001102BCGR is configured for a single output format at time of manufacture (e.g., LVDS *or* Dual CMOS). It cannot switch formats dynamically or drive mixed-signaling loads. However, the Dual CMOS option provides two identical-phase or complementary-phase CMOS outputs, while LVDS mode delivers differential CLK+/CLK− signals. Format selection is locked in the part number and cannot be altered post-shipment.

How does the 541BAA001102BCGR achieve –83 dBc PSNR without external filtering?

The 541BAA001102BCGR achieves –83 dBc typical PSNR through integrated on-die power supply regulation and noise-rejection circuitry within its DSPLL core. This includes dedicated low-noise LDOs, digital supply filtering, and optimized internal routing - eliminating the need for external ferrite beads or LC filters. The specification is validated with 50 mVpp sine-wave ripple injected at 100–1000 kHz, matching real-world SMPS noise profiles.
