Product Information

www.DataSheet4U.com XE0046 02/98 High-Performance Quad DAA Module Description Xecom created the XE0046 for high-performance, multi-line applications. The XE0046 integrates four high performance DAA's into a single compact module. Each DAA circuit operates independently of all the others. Like all of Xecom's DAA modules, the XE00046 integrates a Ring Detect Circuit, Loop Current Holding Circuit, Solid-State Hookswitch, and Telephone Line Transformer for each line. The XE0046 also provides each line with a path for the Caller ID signal from the telephone network and a two-to-four wire convertor. The two-to-four wire convertor separates the receive signal from the transmit signal. Below is a list of the special features incorporated into the XE0046 for high-performance, multi-line applications. XE0046 Features * Four Individual DAA's in a Single Package; * Each DAA supports 33,600 bps data transfer; * Each DAA provides a path for the Caller ID signal from the phone company central office; * Each DAA includes a 2/4 four wire convertor; * Each DAA passes network signaling up to 0 dBm without distortion. * Small Size: 2.5 inches long, 1.5 inches wide, and 0.6 inches high; * FCC Part 68 Compliant; * Individual Ring Detection for each line; * Each DAA integrates a Low-Distortion Telephone Line Transformer; * Each DAA provides a1500 volts isolation between the phone line and all other circuits; * Solid-State Hookswitch Control for each line; XE0046 Block Diagram (This Block Diagram represents each DAA within the XE0046) Caller ID TX RX 2/4 Wire Convertor Line Transformer Line Current Holding Circuit Tip Ring OH Hookswitch RI Ring Detector XECOM XE0046 XE0046 Mechanical Specifications A Dim A B B C D E F F D E F G H J C Notes: These dimensions reflect the module's maximum envelope.

Vdd provides the -5 volt power source to the XE0046 Tip provides the second connection to the telephone network (RJ11 Pin 3) on each of the four internal DAAs. Tip has 1500 volts isolation from the rest of the circuitry. This isolation must be preserved throughout the system. Ring is one of two signals which form the telephone network connection (RJ11 Pin 4) on each of the four internal DAAs. The XE1046 is not sensitive to the polarity of the battery voltage on the telephone line. Ring has 1500 volts isolation from the rest of the circuitry which must be preserved throughout the system. This signal is used as common reference for all of the control signals in the XE0046. Signals on Tip and Ring are not referenced to ground. No Connect Ring Indicate, output, active low, TTL, RI provides a half-wave representation of the Ring appearing on each telephone line. Hook-switch relay control an active high input. A high on OH closes the internal relay within each DAA and connects the equipment to that telephone line. RX is the analog output from each DAA. RX is referenced to ground. The level of RX will be within 1 dB of the received signal on the telephone line. TX is the analog input to each DAA. The signal level at TX will be within 1 dB of the level of the transmitted signal on Tip and Ring. TX is referenced to...
