Product details

Overview

544BAEC002030BBG from Skyworks Solutions is an I²C-programmable ultra-low-jitter crystal oscillator (XO) delivering 150 fs RMS phase jitter (12 kHz–20 MHz), programmable from 0.2 to 1500 MHz with <1 ppb resolution, and supporting LVPECL/LVDS/CMOS/CML/HCSL/Dual CMOS outputs. It operates across –40 to +85 °C with ±20 ppm total frequency stability and is used in high-speed optical networking clocking, FPGA/ASIC timing, and broadcast video systems.

For engineers reviewing the 544BAEC002030BBG datasheet, 544BAEC002030BBG pinout, 544BAEC002030BBG application, or 544BAEC002030BBG equivalent, this page provides verified technical context, package mapping, I²C configuration behavior, output format compatibility, and validated alternative options for timing-critical designs requiring sub-200 fs jitter and multi-voltage (1.8/2.5/3.3 V) operation.

Technical Context

The 544BAEC002030BBG implements Skyworks' 4th-generation DSPLL® architecture with a fixed 55.05 MHz crystal reference and fractional-N feedback divider (FBDIV, 11.32-bit format), enabling precise synthesis of integer and fractional frequencies without external components. Its digital loop filter and on-chip power supply noise rejection (–80 dBc typical PSNR) suppress ripple from switched-mode supplies.

It supports up to four pin-selectable startup frequencies via OE/FS pins, I²C reprogramming at 100 kbps/400 kbps/1 Mbps, and dynamic frequency changes with ≤100 µs settling for small offsets (<±950 ppm) or 40 ms for large transitions. Output enable timing is ≤20 µs, and power-up stabilization occurs within 10 ms.

Equivalent & Alternatives

The following parts are listed as comparable options for similar programmable oscillator applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Si542BAAC002030BBG	Same DSPLL core, but limited to 0.2–1025 MHz range and 200 fs jitter (typ)	Not suitable for >1025 MHz applications like 400G PAM4 or 644.53125 MHz SerDes	Select only if target frequency ≤1025 MHz and jitter budget allows +50 fs margin
Si570ACD000123DG	Legacy I²C-programmable XO with higher 350 fs jitter and no factory-configurable startup pins	Lacks pin-selectable frequency modes and has slower 10 ms I²C write latency	Use only for legacy design refresh where Si544's advanced features are unnecessary

Compared with Si542BAAC002030BBG and Si570ACD000123DG, the 544BAEC002030BBG delivers broader frequency coverage, lower jitter, and faster reconfiguration-making it optimal for next-generation optical and AI-accelerator timing where sub-200 fs performance and field flexibility are mandatory.

FAQ

What output formats does the 544BAEC002030BBG support?

The 544BAEC002030BBG supports LVPECL, LVDS, CML, HCSL, CMOS, and Dual CMOS output formats-all selectable at factory programming. Each format is electrically optimized: LVPECL delivers 1.1–1.9 V_PP swing into 50 Ω to VDD–2.0 V; LVDS provides 0.6–0.9 V_PP differential swing with 100 Ω termination; CMOS offers rail-to-rail outputs with 8/6/4 mA drive strength depending on VDD. The 544BAEC002030BBG does not require external level-shifting circuitry for any supported format.

How is frequency programmed on the 544BAEC002030BBG?

Frequency is programmed via I²C using Skyworks' DSPLL register map: FBDIV (43-bit fractional feedback divider), HSDIV (11-bit integer high-speed divider), and LSDIV (3-bit power-of-2 low-speed divider). The 544BAEC002030BBG accepts standard I²C commands at 100 kbps, 400 kbps, or 1 Mbps. Factory-configured startup frequency is retained in NVM, while runtime updates take effect within 100 µs for small changes (<±950 ppm) or 40 ms for full-range reprogramming-including internal VCO recalibration.

What is the total frequency stability specification for the 544BAEC002030BBG?

The 544BAEC002030BBG has a total frequency stability of ±20 ppm over –40 to +85 °C, covering temperature drift, initial calibration error, load pulling, supply voltage variation, and 20-year aging at 70 °C. This value is guaranteed across all supported output formats and supply voltages (1.8 V, 2.5 V, 3.3 V). Stability is measured per JEDEC JESD22-A114 and MIL-STD-883 methods, with no derating required for standard operating conditions.

Does the 544BAEC002030BBG require external components for operation?

No, the 544BAEC002030BBG operates as a fully integrated solution: the internal DSPLL synthesizer, 55.05 MHz crystal resonator, power regulation, and I²C interface are contained within the 5×7 mm hermetic CLCC package. Only standard decoupling capacitors (0.1 µF ceramic near VDD and GND) are required. No external loop filters, VCO tanks, or termination resistors are needed-the 544BAEC002030BBG drives standard 50 Ω or 100 Ω loads directly per output format specification.

What is the power-up behavior of the 544BAEC002030BBG?

The 544BAEC002030BBG achieves stable output within 10 ms after VDD reaches 90% of nominal (1.8/2.5/3.3 V), with output frequency settling to within final spec. During power-up, the device defaults to its factory-programmed startup frequency and output format. OE pin control is active within 3 µs of power-on, allowing host processors to gate clock delivery before system initialization completes. The 544BAEC002030BBG tolerates VDD ramp rates up to 100 V/ms without malfunction.
