AN1006: Differences Between Si534x/8x Revision B and Revision D Silicon
This document highlights differences between Revision B and Revision D silicon forthe following part numbers:
•Si5340
• Si5341
• Si5342
• Si5344
• Si5345
• Si5346
• Si5347
• Si5348
• Si5380
SUMMARY:
Compared to Revision B, Revision D silicon for Si534x/8x fixes several errata, supports higher maximum output frequency ranges, and offers several new features. This document outlines those differences.
Applies to Si5380/48/47/46/45/44/42/41/40:
With the release of Revision D for Si534x/8x, the Revision B devices are now classified as "Not Recommended for New Designs"(NRND). As of the Revision D release date, Silicon Labs has no plans to EOL the Si5348/47/46/45/44/42/41/40 Revision B devices and will continue production of both the Revision B devices and the newer Revision D devices. As of the Revision D release date, Silicon Labs does not plan to continue production of Si5380 Revision B devices. Customers using Si5380 must follow the instructions below to migrate their existing Revision B designs to Revision D.
Revision D devices are pin-compatible and footprint-compatible with Revision B devices. However, Revision D devices are not intended to be drop-in replacements for Revision B devices. As a result of changes to the circuitry in Revision D devices, their performance and behavior will not completely match that of Revision B.
• Customers currently using Si5348/47/46/45/44/42/41/40 Revision B in production may continue to do so. Silicon Labs will maintain production of both Revision B and Revision D concurrently.
• Customers who wish to migrate a design from Revision B to Revision D should download the latest version of ClockBuilder Pro and create a new custom OPN for Revision D with their desired configuration. Once a new Revision D OPN has been created, customers should verify functionality of the device in their system prior to starting production with Revision D.
• Silicon Labs does not recommend writing a register file, settings file, or regmap that was created for Revision B to a Revision D device. When migrating an existing design from Revision B to Revision D, customers should download the latest version of Clock-Builder Pro and create new register files, settings files, or regmap exports to be used with Revision D.
