Product Description ____________________
|
|
The
AFE is a purely
analog bi-directional transceiver for E1 NIU and ISDN Primary Rate Interface
(ISDN PRI) application at 2.048Mbps (E1). This transceiver operates
over 2 km of 0.4mm twisted-pair cable without any external components.
It is built using an advanced double-poly, single-metal CMOS process
and requires only a single 3.3-volt power supply.The Silway AFE finds
applications in widely diverse areas of Telecommunication
