Product Information

www.DataSheet4U.com XE0052S &XE0052T 5/99 Slim V.34 Telephone Line Interface with 2/4 Wire Hybrid Description The XE0052S and XE0052T are compact telephone interface modules which support V.34 communications at data rates to 33,600 bps yet are just 0.31 inches thick and comply with FCC Part 68 Rules for connection to the public telephone network. The XE0052S and XE0052T are complete DAAs. They include the 2-4 wire convertor to separate transmit and receive signals, ring detection, and the switch hook to control line access. The two models differ only in their RI outputs. The XE0052S has an integrated RI output which remains low for the duration of the ring. The XE0052T RI output is not integrated and provides a pulse train at twice the ring frequency. Xecom offers two mechanical variations for each of the XE0052S and XE0052T. The XE0052S1/T1 mount vertically to consume minimal board space. The XE0052S2/T2 mount horizontally to maintain a low profile. Both versions are electrically identical and share the same pin configuration.

The Ring pin has 1500 volts isolation from the rest of the circuitry. This isolation must be preserved throughout the system. Tip Connection to the phone line (RJ11 Pin 3). The Tip pin has 1500 volts isolation from the rest of the circuitry. This isolation must be preserved throughout the system. Hookswitch relay control. A high on OH closes the internal relay and connects the equipment to the telephone line. TX provides the analog input signal to the 2-4 wire convertor of the XE0052S. TX uses a 2.5 volt reference signal and therefore must be capacitively coupled to the host equipment. Ground +5 Volts supply power RX provides the analog output signal from the 2-4 wire converter of the XE0052S. RX uses a 2.5 volt reference signal and therefore must be capacitively coupled to the host equipment. Ring Indicate, output, active low, TTL. On the XE0052S a low on /RI indicates the modem is receiving a ring signal. The XE0052T provides a pulse string at twice the ring frequency when a ring is detected. 2 Tip --- 3 OH I 4 TX I 5 6 7 GND VCC RX ---O 8 /RI O XE0052 Absolute Maximum Ratings Storage Temperature Operating Temperature Range Maximum Lead Temperature (soldering 2 seconds per wave) -25 C to +85 C 0OC to +70OC 260OC O O XECOM (4) XE0052 XE0052 Electrical Specifications (VCC = 5V + 10%, Ta = 0 to 70C) Parameter Power Supply Current Transmit Inserti...
