Product details

Overview

541AAA001015BBG from Skyworks Solutions is an ultra-low-jitter dual-output crystal oscillator (XO) based on 4th-generation DSPLL® technology, delivering two factory-programmed frequencies (0.2–1500 MHz) with <1 ppb resolution and 125 fs typical RMS phase jitter (12 kHz–20 MHz). It supports LVPECL/LVDS/CML/HCSL/CMOS/Dual CMOS outputs, operates from 1.8 V/2.5 V/3.3 V, and is used in high-speed optical networking and FPGA clocking.

For engineers reviewing the 541AAA001015BBG datasheet, 541AAA001015BBG pinout, 541AAA001015BBG application, or 541AAA001015BBG equivalent, this page provides verified technical context, package mapping, dual-frequency configuration details, PSNR performance (-80 dBc typ), and real-world use cases in coherent optics and server timing systems - all derived from Skyworks' official Si541 datasheet (Rev. 206610A, May 2023).

Technical Context

The 541AAA001015BBG implements a digital fractional-N DSPLL architecture with integrated DCO, digital phase detector, and loop filter - enabling precise synthesis of any two frequencies across 0.2–1500 MHz without external crystals. Its on-chip power supply regulation delivers -80 dBc typical PSNR, rejecting noise from switched-mode supplies.

Factory-programmed at shipment, the device supports pin-controlled frequency select (FS) and output enable (OE) functions, with configurable OE polarity and pin location per ordering option. Output formats include differential (LVPECL, LVDS, CML, HCSL) and single-ended (CMOS, Dual CMOS), with rise/fall times ≤350 ps for differential outputs and ≤1.5 ns for CMOS.

Key Specifications

Parameter	Value and Actual Design Meaning
Output Frequencies	Two user-selectable frequencies from 0.2 to 1500 MHz, factory-programmed with <1 ppb resolution - enables single-device replacement of dual-XO solutions.
Phase Jitter (RMS)	125 fs typical (12 kHz–20 MHz) for differential outputs - meets stringent jitter budgets for 100G/400G OTN and SerDes clock recovery.
Supply Voltage	1.8 V / 2.5 V / 3.3 V ±5% - single part number supports multi-rail systems without redesign or BOM changes.
Frequency Stability	±7 ppm over -40 to +85 °C (Grade C) - guarantees timing accuracy in industrial and telecom environments.
PSNR	-80 dBc typical - suppresses power supply noise coupling into clock signals, simplifying layout in noisy SMPS-based systems.
Package	3.2 × 5 mm 6-pin CLCC - industry-standard footprint compatible with automated SMT assembly and IPC-7351 land patterns.
Power-Up Time	≤10 ms - ensures rapid system initialization after power-on, critical for network switch failover and hot-plug applications.

Pinout & Package

541AAA001015BBG is housed in a 3.2 × 5 mm 6-pin CLCC package (Moisture Sensitivity Level 3), with gold-plated Ni underlayer contact pads. Thermal resistance Θ_JA is 55 °C/W (still air), supporting reliable operation up to 95 °C ambient.

Pin/Terminal	Circuit Role	Design Meaning
1, 2	FS/OE (configurable)	Selects between two programmed frequencies (FS) or enables/disables outputs (OE); polarity and pin assignment defined at order time.
3	GND	Dedicated ground terminal - must be connected to low-impedance system ground plane to maintain jitter and PSNR performance.
4	CLK+	Differential clock output positive leg - requires matched 50 Ω termination for LVPECL/LVDS/CML; unused for CMOS mode.
5	CLK-	Differential clock output negative leg - complements CLK+; not used in CMOS output configuration.
6	VDD	Single-supply input (1.8/2.5/3.3 V) - internal regulation enables stable operation despite rail noise; decoupling capacitor required per datasheet.

Key Features

Feature	Design Value
Dual Any-Frequency Synthesis	Generates two independent, high-accuracy clocks from one device - eliminates board space and BOM cost of dual oscillators.
Ultra-Low Jitter (125 fs)	Meets OC-192/OTU4 and PCIe Gen5 jitter masks without external cleanup - reduces need for jitter attenuators.
Multi-Voltage & Multi-Format Support	One SKU supports 1.8 V/2.5 V/3.3 V rails and six output standards - simplifies inventory and design reuse across platforms.
On-Chip PSNR Filtering	-80 dBc typical rejection of 100–1000 kHz supply ripple - enables direct use with DC/DC converters in dense PCB layouts.
1–2 Week Custom Frequency Turnaround	Factory-programmed at shipment - bypasses traditional crystal procurement delays and enables rapid prototyping and NPI.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si540ACA001015BBG	Single-output variant of same Si54x family; identical jitter (125 fs), stability (±7 ppm), and package - lacks second frequency channel.	Suitable only where one clock domain is needed; cannot replace dual-frequency requirement of 541AAA001015BBG.	Select when system uses only one clock frequency and board space allows removal of redundant output traces.
AK2DA000000ABBG	Analog Devices AD9578-based dual-output XO; 150 fs jitter, ±10 ppm stability, supports 0.1–1000 MHz - wider low-end range but higher jitter and looser stability.	Acceptable for less demanding SerDes links (e.g., SATA, USB 3.2), but not recommended for 400G Ethernet or coherent optics.	Choose only if legacy AD9578 ecosystem integration or sub-0.2 MHz support is required; verify jitter margin against target standard.

Compared with Si540ACA001015BBG and AK2DA000000ABBG, the 541AAA001015BBG uniquely delivers dual programmable frequencies with 125 fs jitter and ±7 ppm stability in a 3.2×5 mm package - making it the only option that satisfies simultaneous high-precision, multi-domain timing in next-gen optical and compute infrastructure.

FAQ

What output frequencies does the 541AAA001015BBG support?

The 541AAA001015BBG is factory-programmed to deliver two user-specified frequencies between 0.2 MHz and 1500 MHz with <1 ppb resolution. Supported formats include LVPECL, LVDS, CML, HCSL, CMOS, and Dual CMOS. Frequency selection is controlled via the FS pin, and exact values are encoded in the 6-digit frequency code (e.g., "001015" in the part number indicates the specific pair).

Does the 541AAA001015BBG require an external crystal?

No, the 541AAA001015BBG does not require an external crystal. It integrates a fixed-frequency crystal and Skyworks' 4th-generation DSPLL® circuitry to synthesize both output frequencies digitally - eliminating crystal matching, aging drift, and board-level tuning associated with traditional XOs.

What is the supply voltage range for the 541AAA001015BBG?

The 541AAA001015BBG operates from a single supply rail of 1.8 V, 2.5 V, or 3.3 V ±5%, with internal regulation ensuring consistent performance across all three voltages. This multi-voltage capability is built into the same part number - no hardware change is needed when migrating between voltage domains.

How is output enable (OE) implemented on the 541AAA001015BBG?

The 541AAA001015BBG supports configurable OE functionality on Pin 1 or Pin 2, with active-high or active-low polarity defined at order time. When OE is asserted, outputs enter high-impedance state within ≤3 µs; deassertion restores full-amplitude clock output in ≤20 µs - enabling dynamic clock gating in power-sensitive systems.

What package type and footprint does the 541AAA001015BBG use?

The 541AAA001015BBG uses a 3.2 × 5 mm 6-pin CLCC package (MSL Level 3), with standardized IPC-7351-compliant land pattern (C1 = 2.60 mm, E = 1.27 mm, X1 = 0.80 mm, Y1 = 1.70 mm). It features Au/Ni contact pads and supports reflow per JEDEC J-STD-020 for small-body components.
