It serves as a high-stability, reconfigurable clock source for coherent optical transceivers and FPGA timing.

For engineers reviewing the 544BBJB002384CCGR datasheet, 544BBJB002384CCGR pinout, 544BBJB002384CCGR application, or 544BBJB002384CCGR equivalent, this device offers factory-configured startup frequency, I²C address, output format, and OE pin polarity - enabling rapid integration into 100G/400G OTN, broadcast video, and server clocking systems without custom crystal procurement.

Technical Context

The 544BBJB002384CCGR implements Skyworks' 4th-generation DSPLL® architecture with a fixed 55.05 MHz crystal reference, fractional feedback divider (FBDIV, 11.32-bit), integer high-speed divider (HSDIV, 5–2046), and power-of-2 low-speed divider (LSDIV, 1–32). Its digital loop filter and on-chip power supply regulation deliver –80 dBc typical PSNR and maintain sub-200 fs jitter across integer/fractional frequencies.

It supports dual startup frequencies via pin-selectable FS0/FS1 inputs, I²C reprogramming at 100 kbps/400 kbps/1 Mbps, and operates from 1.8 V, 2.5 V, or 3.3 V supply - all on the same part number. Output enable (OE) is configurable for active-high/low on Pin 1 or Pin 2 per ordering option.

FAQ

What output frequency ranges does the 544BBJB002384CCGR support?

The 544BBJB002384CCGR supports 0.2–1500 MHz for LVPECL/LVDS/CML outputs, 0.2–400 MHz for HCSL, and 0.2–250 MHz for CMOS/Dual CMOS. This range covers key standards including 156.25 MHz (10G Ethernet), 644.53125 MHz (400G-FR4), and 297 MHz (12G-SDI). Frequency is set via I²C or factory-programmed startup values - no hardware change required.

How is the 544BBJB002384CCGR's 150 fs phase jitter validated?

The 150 fs RMS phase jitter (12 kHz–20 MHz) for the 544BBJB002384CCGR is measured per IEEE 1139 using Agilent E5052B with differential-to-single-ended conversion, across >700 common frequencies including 156.25 MHz and 644.53125 MHz LVDS outputs. It is guaranteed by characterization - not typical-only - and applies to all supported output formats within their respective frequency limits.

Can the 544BBJB002384CCGR replace legacy fixed-frequency XOs in existing designs?

Yes - the 544BBJB002384CCGR uses standard 3.2×5 mm CLCC packaging and pin-compatible footprints with many fixed XOs. Its factory-programmed startup frequency, OE polarity, and I²C address allow drop-in replacement without layout changes. Unlike traditional XOs, it eliminates crystal qualification and long lead times while maintaining identical board-level integration.

What power supply noise rejection does the 544BBJB002384CCGR provide?

The 544BBJB002384CCGR delivers –80 dBc typical power supply noise rejection (PSNR), verified with 50 mVpp ripple at 100–1000 kHz injected on VDD. This on-chip filtering enables reliable low-jitter operation directly from noisy switched-mode power supplies - removing the need for additional LDOs or ferrite beads in space-constrained optical module designs.

Does the 544BBJB002384CCGR support dual-output configurations?

Yes - the 544BBJB002384CCGR offers Dual CMOS output option (ordering code F or G), providing two identical or complementary CMOS clocks from a single device. This replaces two discrete oscillators in clock fanout applications, reducing PCB area, BOM cost, and skew between channels - with guaranteed matching <50 ps between outputs.
