CH1817 - Family of Low Profile DAA Modules

General Description

DataSheet4U.com Ring Detection.

Referring to the block diagram in Figure 1, incoming ring detection is performed by the CH1817 and the RI pin is set Low during the 2 second (typical) ring period and is restored to High for the 4 seconds (typical) between rings.

www.DataSheet4U.com CH1817 Family of Low Profile DAA Modules INTRODUCTION The CH1817 is a Family of Low Profile Data Access Arrangement (DAA) Modules. They are compatible with all modem chip sets. These devices have been tested to meet or exceed FCC Part 68 requirements and are Canadian DOC approvable. They are also recognized by Underwriters Laboratories to UL 1459 Specifications. The CH1817 modules are ultra small (1.0” x 1.0” x0.35”) affording an easy integration into spacesensitive designs, including laptop and hand-held computer based products. The CH1817 family of products may be socketed or mounted directly onto a Printed Circuit Board (PCB). The telephone line connection is made through TIP and RING to an RJ-11 jack or equivalent.
