Now in Stock: 570FBB000105DG | Skyworks Solutions Inc. I2C-Programmable Crystal Oscillator (XO) | Brand New, Fully Traceable, and Ready to Ship!

The 570FBB000105DG is an I2C-programmable crystal oscillator (XO) from Skyworks Solutions Inc., built for low-jitter clock generation in telecom, networking, and high-speed data equipment. Design and procurement teams working on SONET/SDH line cards, 10 Gigabit Ethernet hardware, or optical transport modules choose this part when they need a stable, reprogrammable reference clock in a single compact device.

The 570FBB000105DG belongs to Skyworks' Si570 family, a range of any-frequency oscillators that use third-generation DSPLL technology to deliver low phase jitter across 10 MHz to 1.4 GHz. It ships in an industry-standard 8-pad, 5 x 7 mm surface-mount package and is Pb-free and RoHS compliant. Here is a closer look at what the part offers.

Key Features of the 570FBB000105DG

I2C-Reprogrammable Output Frequency

The device is factory-configured to a 622.08 MHz start-up frequency and can be reprogrammed over its I2C serial interface. One part number can cover multiple clock rates, which reduces the number of unique oscillators a design needs to qualify and stock.

Low-Jitter DSPLL Performance

Skyworks' third-generation DSPLL architecture gives the Si570 family a typical phase jitter of around

0.3 ps RMS. That level of timing purity suits high-speed serial links where clock noise directly affects bit error rates.

2.5 V LVDS Differential Output

The "F" option code specifies a 2.5 V supply with an LVDS differential output and an active-high output enable. LVDS signalling provides clean, noise-resistant clock distribution for high-frequency board layouts.

Compact Surface-Mount Package

The 8-pad, 5 x 7 mm no-lead package mounts directly to the PCB and fits standard high-density layouts. Its small footprint helps engineers reclaim board space on dense line cards and transceiver modules.

High Stability and Reliability

An internal fixed crystal gives the part roughly three times better frequency stability than SAW-based oscillators, with guaranteed aging performance over the life of the device. This makes it a dependable reference for equipment that must run for years without recalibration.

Pb-Free and RoHS Compliant

The 570FBB000105DG meets Pb-free and RoHS requirements, so it drops into compliant manufacturing processes without additional review.
