ADSL SMD Line Interface Hybrid

APC78142

OPERATING TEMPERATURE -40°C TO +85°C

FEATURES

•

APC78142 is designed to interface with Alcatel’s MTK20150 ADSL transceiver chipset. The

SMD mechanical form is designed to optimize Central Office (CO) high density line card

applications. The hybrid contains every component required between the analog front end chip and the connector,

including line interface transformer and receive filters (excluding the line driver and associated resistor network).

Approval is pending for BS EN60950 / IEC60950 / TS 001 / AS/NZS 3260 / CAN/CSA C22.2 Np. 950-95 / UL1950 / UL

Component Recognition and CB Certificate.
