Silicon Change: Silicon Labs is pleased to announce the availability of revision B silicon for the Si5338/35/34/56A/56B. Revision B improves operation in spread spectrum clock generation applications by fixing an erratum related to down spread and by updating how the device is configured for center spread applications. The device datasheets have been updated to remove all device errata, highlight new configuration requirements for center spread operation and provide updated orderable part number information. 2. Package Lead Frame Change: The lead frame is being modified on all Si5338/35/34/30/55/56A/56B devices to improve overall manufacturability and capacity. The new lead frame makes a minor change in the lead shape as shown in the table below. This minor change is negligible and does not require changes to the PCB land pattern. NOTE: All revision B products use the new lead frame. Revision A products may use either the current lead frame or the new lead frame after the PCN effective date (15 May 2013). Current Lead-frame New Lead-frame Customers are encouraged to transition to revision B as soon as possible. However, as a courtesy to customers Silicon Labs will support extended revision A order and shipment dates beyond the PCN effective date. Please see the “Last Date of Unchanged Product” section below for these extended deadlines.

The document is uncontrolled if printed or electronically saved. Pg 1 Process Change Notice #1301151 ____________________________________________________________________________________________________ Reason for Changes: 1. Revision B corrects an erratum in the affected devices’ down spread spectrum operation. Information concerning the spread spectrum operation of revision B is documented in the updated datasheets of all affected part numbers. See the datasheets for updated information about changes to center spread configuration and operation of revision B. The datasheets are available at www.silabs.com. If you have questions about the revised datasheet, please see your Silicon Labs’ Sales Representative. A list of Silicon Labs’ Sales Representatives is also available at www.silabs.com 2. Silicon Labs’ package supplier modified the current lead-frame to improve manufacturing efficiency. Impact on Form, Fit, Function, Quality, Reliability: There are no changes to Fit, Quality or Reliability. Form: There is a minor change to the lead shape as shown in “Description of Change.” Customers do not need to make any changes to their PCB design or manufacturing process to accommodate this change. Function: Revision B corrects an erratum with the down spread spectrum feature. See the datasheets for updated information about changes to center spread configuration and revision B operation.

Pg 2 Process Change Notice #1301151 ____________________________________________________________________________________________________ Product Identification: 1. Silicon Change (Rev B) Identification: All products with orderable part numbers (OPNs) listed below are affected. Please see the datasheet’s ordering guide for complete information. OPN Prefix Si5338 Si5334 Si5356A, Si5356B Si5355 Si5335 Si5330 OPN Examples Tubes or Trays Ordering Option Tape & Reel Ordering Option (non Tape & Reel option) (OPN ends in an “R” suffix) Si5338X-A-GM Si5338X-A-GMR Si5338X-Axxxxx-GM Si5338X-Axxxxx-GMR Si5334X-Axxxxx-GM Si5334X-Axxxxx-GMR Si5356X-A-GM Si5356X-A-GMR Si5356X-Axxxxx-GM Si5356X-Axxxxx-GMR Si5355X-A-GM Si5355X-A-GMR Si5355X-Axxxxx-GM Si5355X-Axxxxx-GMR Si5335X-Axxxxx-GM Si5335X-Axxxxx-GMR Si5330X-Axxxxx-GM Si5330X-Axxxxx-GMR Key: (1) X = device or functional grade; (2) xxxxx = NVM or customer specific code. How to order Rev B of your existing Rev A part number: All existing Rev A part numbers have Rev B equivalent part numbers available for immediate ordering. The new part numbers use the same part number convention but change the revision to “B” as denoted in the datasheet ordering guide and the example below. Example: If using revision A part number Si5338C-A01909-GM, revision B of this part number is Si5338C-B01909-GM. The datasheet addendum for any custom device can be downloaded using the online lookup utility: http://www.silabs.com/products/clocksoscillators/clock-generatorsand-buffers/Pages/clockbuilder-lookup.aspx. How to configure a new custom Rev B part number: For the Si5338/34/56A/56B: Use ClockBuilder Desktop software (version 6.0 or later) to generate an NVM file for new custom part numbers: http://www.silabs.com/Support%20Documents/Software/ClockBuilderDesktopSwInstall.zip NVM files created by earlier versions of the ClockBuilder Desktop software cannot be used to create new part numbers. For the Si5335/55: Use the online ClockBuilder Web utility at: http://www.silabs.com/products/clocksoscillators/Pages/ClockBuilderStart.aspx. Lead frame change product identification: Revision A products marked with a date code (YYWW) of “1314” (Year = 2013, Work week = 14) or later use the new lead frame. Refer to the marking diagrams in the datasheets for more information. All revision B products use the new lead frame. Last Date of Unchanged Product: Last shipment of products with existing lead frames: 15 May 2013 Last orders accepted for Revision A: 15 Aug 2013 Last shipments of Revision A: 15 Feb 2014 2.
