56 KBPS DAA in a PLCC Package
Description
Xecom’s XEV90 is a complete DAA integrated into a
compact PLCC package. The XEV90 supports analog
data transfer to 56 KBPS. The 68-Pin PLCC package
permits automated, high-volume assembly.
The XEV90 does not sacrifice performance for small size
and surface-mount convenience. The heart of the XEV90
is a proprietary, low profile, low distortion transformer.
This wide bandwidth, low distortion device provides the
clear signal path required for 56 KBPS analog data
transfer.
Like all Xecom DAA's the XEV90 is a complete
telephone line interface. It includes the telephone line
transformer, line current holding circuit, hookswitch and
ring indicator. The XEV90 replaces the dozens of
components found in a discrete DAA design.
