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.
