Surface-Mount DAA for Audio Data Transfer
Description The XE0092 supplies a complete telephone line interface or DAA (Data Access Arrangement) in a compact, surface-mount module. It offers an alternative to a discrete DAA for a multitude of voice, audio, DTMF, fax and data applications. The XE0092 replaces 25 to 30 discrete components with a single, fully-assembled and fully tested unit. The XE0092 does not sacrifice performance for small size and surface-mount convenience. The wide bandwidth, low distortion design provides sufficient bandwidth for a 56K bps analog modem. Like all Xecom DAA's the XE0092 is a complete DAA. It includes a 2-4 wire converter, loop current holding circuit, hook switch and ring indicator. It also supports Caller ID and remote disconnect detection. The XE0092 complies with FCC Part 68 rules for direct connection to the telephone line. Features * Low-profile, surface-mount package: 1.20" by 1.00" by 0.30" * Meets line interface requirements for reliable V.90 and V.92 communications; * Typical Second Harmonic Distortion of -80 dB; * Part 68 Compliant; * Integrated 2-to-4 wire converter provides 34 dB Transhybrid Loss * Supports detection of incoming Caller ID signals; * Integrated Ring Detection, * Low power operation: Just 10 millamps from a single + 3.3 Volt Power Supply; * Solid-State Hook switch Control; * Monitors local loop current reversal to detect a remote telephone line hang-up;

1 2 VCC TX-
Description
+3.3 or 5 Volt power source for the XE0092. VCC powers the RI and OH control lines. TX- is the negative half of the differential transmit data input to the XE0092 from the host system. If the host system uses a single ended transmit data output, that output should be connected to TX- and TX+ should be grounded. TX+ is the positive half of the differential transmit data input to the XE0092 from the host system. If the host system uses a single ended transmit data output, that output should be connected to TX- and TX+ should be grounded. Switch-hook control to the modem. /OH is an active low input. Activating OH closes the switch-hook causing the XE0092 to seize the local telephone line. The telephone line connection is dropped when OH is deactivated. The host can pulse OH to simulate rotary dialing. The pulse rate in the US is ten pulses per second. Each digit is dialed as a series of pulses created by closure of the hook-switch, one pulse for the digit one to ten pulses for the digit zero. The pulses must be asymmetrical so that the hook-switch is closed for thirty-one milliseconds and open for sixty-nine milliseconds. An inter-digit delay of at least one hundred milliseconds is required.

/RI
Ring Indicate output from the module. /RI is active low. RI goes low for the duration of each incoming ring, returning high between rings. The XE0092 recognizes ring voltages of twenty-eight to one hundred fifty volts RMS in the frequency range of sixteen to sixty-eight Hertz. When the XE0092 is off-hook the /RI output indicates a remote disconnect. The local loop current reversal triggered by a disconnect on the far end of the telephone line causes /RI to go active for about 1 second. /CID is an active low input to the XE0092. The host drives /CID low after the first ring to permit the Caller ID signal to be presented on the RX outputs. The telephone network normally sends Caller ID information on incoming calls between the first and second ring. RX- is the negative half of the differential received data output from the XE0092. If the host system uses a single ended received data input, that input should be connected to RX+ and RX- should remain open.
