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
