www.DataSheet4U.com XE0002D August 2005 Modular DAA with 2/4 Wire Convertor Description The XE0002D is a compact DAA module designed for applications requiring voice, data or fax transfer. It complies with FCC Part 68 rules for direct connection to the public switched telephone network and also supports leased line applications. The XE0002D provides a complete telephone interface. It includes the 2/4 wire convertor to separate transmit and receive signals, ring detection, integral switch hook and telephone line transformer. All of this circuitry is integrated into a module requiring only 1.25 inches of board space. Features: • Small Size: just 1.25 inches by 1.0 inches by 0.32 inches high • FCC Part 68 Compliant • User selectable 2-4 wire convertor • Active Low Ring Detection • Integral Switch Hook • Supports V.32 Data Transfer • Supports both dial-up and leased line applications • Extended Operating Temperature Range (-40C to +85C) available XE0002D Block Diagram /OH HookHook -Switch XMIT RCVR XFMR T1 T2 J2 J1 2/42/4 - Wire Conve rter Tip Telephone Line Transforme r Loop Curre nt Holding Circuit Ring /RI Ring Detect Jumpers J1 and J2 must be installed to connect the 2 to 4 wire convertor.

VCC supplies +5 Volts power to the XE0002D Ring Indicate, output, active low, TTL. /RI indicates the XE0002D is receiving a ring signal. /RI remains low for the duration of each ring. RCVR acts as the analog output from the XE0002D’s 2 to 4 wire converter. Signals pass from the telephone line to the host via RCVR XMIT provides the analog input to the XE0002D’s 2 to 4 wire converter. Signals placed on XMIT are sent out onto the telephone line. XFMR is provided to connect the internal 2 to 4 wire converter to the telephone line transformer. A jumper is required from XFMR to T1 whenever the 2 to 4 wire circuit is required. T1 is one of two direct connections to the internal telephone line transformer. T1 must be connected to the XE0002D XFMR lead to use the internal 2 to 4 wire converter. If the 2 to 4 wire converter is not required, Signals for the telephone line can be passed across T1 and T2. Hookswitch relay control. A high on OH closes the internal relay and connects the equipment to the telephone line. Gnd provides the ground reference connection to the XE0002D. T2 is one of two direct connections to the in.
