Specifications of XE056LCC-2

Lead Free Status / Rohs Status
Supplier Unconfirmed
Description
The XE056LCC is a complete telephone line
interface or DAA supporting 56K bps data transfer
in a leadless, surface-mount package. It is an
alternative to discrete DAA’s for high-speed dial-
up communications. The XE056LCC replaces 25
to 30 discrete components.
In spite of being less than 1 inch square, the
XE056LCC does not sacrifice performance for its
small size and surface-mount convenience. The
wide bandwidth, low distortion design supports
data transfer with even V.90 and V.92 modulation.
The XE056LCC includes the telephone line
transformer, loop current holding circuit, hook-
switch and ring indicator. The XE056LCC
complies with FCC Part 68 rules for direct
connection to the telephone line.

... XE056LCC PCB Layout Recommendations The XE056LCC is a leadless part. The pads on your printed circuit board must align with the pads on the bottom of the DAA mdule. Below is the recommended PCB layout. Do not place trace or components under the DAA as this could compromise the network isolation. ...

... Slim-Link PLCC Soldering Instructions Because of its Hybrid construction, the XE056LCC DAA is subject to damage if over exposed to heat during solder reflow operations. Following the soldering instructions below will ensure that the process of soldering the module to the board does not damage the DAA. ...

... Insertion Loss: There is some loss of signal strength as the signal passes through the DAA. This "insertion" loss should be considered when placing signals across T1 and T2 for transmission. The typical insertion loss of the XE056LCC is 6 dB. Total Harmonic Distortion: Total harmonic distortion measures the quality of the DAA signal path quality ...

... The 2/4 wire convertor separates these signals at the host interface. Most modem analog front end chips incorporate an internal 2/4 wire convertor. If you are using the XE056LCC for an application other than a modem, such as audio, or your modem analog front end does not provide the 2/4 wire convertor, you will need to provide a discrete 2/4 wire convertor ...
