CH1817

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. The CH1817 is intended for use with FAX/modem chip sets that have a data throughput of up through V.32bis. For High Speed Applications, Cermetek recommends the CH1837A.
