W93910
ERMES PAGING DECODER
Publication Release Date: Auguest 1999
- 1 - Revision A1
GENERAL DESCRIPTION
The W93910 is a low-power ERMES (Enhanced Radio MEssage System) paging protocol decoder
using a single 100 kHz crystal. The W93910 supports individual call, group call, long message,
changing character set and remote programming functions. To enhance the sensitivity of the pager
system, a digital filter and DPLL are incorporated to remove noise and lock the signal. For convenient
pager programming, the W93910 provides fully software-programmable options and also offers an
independent LED frequency output.
With built-in flexible RF power saving control, frequency synthesizer enable control, quick charge
controls, as well as automatic channel scan algorithm, the W93910 can combine with different RF
receivers to construct a high performance, low power dissipation pager system.
