SI5010-BM

Overview

The Si5010-BM is a fully integrated clock and data recovery (CDR) IC designed for high-speed serial communication systems operating at OC-12/3 or STM-4/1 data rates. It utilizes DSPLL technology to eliminate external loop filter components, reducing noise susceptibility and ensuring optimal jitter performance. The device operates from a single 2.5 V supply over the industrial temperature range of –40 to 85 °C. Key electrical specifications include a typical power dissipation of 293 mW at OC-12, an RMS jitter generation of 1.6 mUI, and a differential output voltage swing of 780–1260 mVpp into a 100 Ω load.

Feature Summary

• DSPLL technology eliminates external loop filter components
• Supports OC-12/3 and STM-4/1 data rates
• Low power consumption: 293 mW typical at OC-12
• Exceeds SONET/SDH jitter specifications

Applications

• SONET/SDH routers
• Add/drop multiplexers
• Digital cross connects
• Board level serial links
• Optical transceiver modules

Procurement Notes

Verify the ordering suffix 'BM' corresponds to the 20-pin QFN package with 85/15 Pb/Sn lead finish and an operating temperature range of –40 to 85 °C. Confirm that the source document identifies Silicon Laboratories as the manufacturer, noting that Skyworks Solutions Inc. acquired Silicon Labs. Ensure the component matches the specific die revision and part designator listed in the top mark section of the datasheet.

Selection Notes

Select the Si5010-BM for applications requiring compliance with Bellcore GR-253-CORE and ITU-T G.958 jitter specifications. The device supports multi-rate operation via the RATESEL pin, allowing configuration for 155.52 Mbps (OC-3/STM-1) or 622.08 Mbps (OC-12/STM-4). Ensure the system provides a stable 2.5 V supply and a reference clock within the specified frequency tolerance of ±100 ppm.

Part Context

The Si5010 is part of a family of CDR devices including the Si5018 and Si5020. The Si5010 specifically targets SONET/SDH applications at OC-12/3 and STM-4/1 speeds. The 'GM' suffix variant offers a matte tin (Pb-free) finish, while the 'BM' variant uses lead-tin plating. Both share identical electrical characteristics and package dimensions.
