The ADSP-21xx family was a very popular legacy DSP used in applications with long-term embedded systems for industrial controls and avionics customers.
The ADSP-21xx support for Waters Corporation began by supplying end-of-life (EOL) finished goods. Then Rochester manufactured product utilising Analog Devices die, which was acquired thru a strategic wafer buy. When that product supply was exhausted, Rochester transitioned Waters to a Rochester product replication/re-creation model by utilising licensed Analog Devices IP.
The strong partnership with Analog Devices enabled and authorised Rochester Electronics to replicate the ADSP-2101 product and bring it back into active status. The ADSP-2101 EOL notice was in 2014 so limited stock remained of the original wafer material. Analog Devices provided Rochester Electronics with the source design, technology, and test databases. Waters had on-going demand for many years to come. Rochester successfully re-created the ADSP-2101 in the PLCC package in February 2018, only 9 months after the IP was first received from Analog.
Rochester contracted with a former ADI DSP resource to consult on the test and analysis of this product to ensure a quick, e?cient, and effective test characterisation and comparison between original ADI silicon and Rochester’s silicon.
This was a highly successful and combined effort of design, supplier, and test teams within Rochester to bring this device back to market in conjunction with a dedicated partner in Analog Devices.
Voice of the Customer
“At Waters, our products stay in the field for 30 years; obsolescence can be a big concern for us. Our best-selling product, Alliance, is 30 years old and this is where the ADSP-2101 was utilised. I see this collaboration between Analog Devices, Rochester Electronics and Waters as the gold standard of how a last time buy should be handled.”
