A series of ADSL transformers developed to work with chipsets manufactured by Analog Devices are available in four designs with either UL1459 or UL1950 3rd edition safety-approved compliance. The transformers are designed to interface with ADI's AD20MSP930 chipset. ADSL and other DSL interfaces allow high data rate transmission over existing telephone copper lines. Pricing for the new designs ranges from $1.50 to $2.50 each/10,000.
