Reason for Change
On Oct 21, 2019, Silicon Labs completed the transaction to acquire Qulsar’s IEEE 1588 precision time protocol (PTP) software
and modules; which represents Qulsar’s complete family of embedded products. The integration of Qulsar products into Silicon
Labs will result in a few relatively minor changes as described below:
1. Existing customer purchase orders shipped beginning on Oct 22, 2019 will be fulfilled and shipped from locations through
Silicon Labs ERP system.
New ship-from locations:
Silicon Laboratories International Pte. Ltd.
18 Tai Seng Street #05-01,
18 Tai Seng, Singapore 539775
Silicon Laboratories
400 West Cesar Chavez
Austin Texas 78701
USA
2. The Qulsar labels will transition as inventory is depleted to standard Silicon Labs labels.
3. All boxes, reels, trays, and moisture barrier bags will transition to Silicon Labs standard materials as inventory is depleted.
4. The commercial invoice (pro forma) and packing list will change to the Silicon Labs standard format starting October 22, 2019.
5. Notification on software changes will be managed separately as they occur.
The following Qulsar ordering part numbers [OPN] will be transitioned to new OPN to accommodate Silicon Labs Enterprise
software (SAP) and all new orders for these parts will reflect the new part numbers.
