PLCC Packaged DAA for Europe and North America
XEV90C
June 2000
Description
Xecom’s XEV90C is a complete, multi-national DAA
integrated into a compact PLCC package. The XEV90C
supports analog data transfer to 56 KBPS and complies
with both FCC Part 68 Rules and the Pan-European
CTR21 specifications. The modified 68-Pin PLCC
package permits automated, high-volume assembly.
The XEV90C does not sacrifice performance for small
size and surface-mount convenience. The heart of the
XEV90C 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.
The XEV90C is a complete telephone line interface. It
includes the telephone line transformer, line current
holding circuit, Caller ID Passthrough circuit,
hookswitch and ring indicator with line connect detect.
The XEV90C replaces the dozens of components found
in discrete and transformerless DAA designs.
