The CYG2911 is a Data Access Arrangement (DAA) module providing a complete telephone line interface circuit in a small 1.07" x 1.07" x 0.4" plastic package. This module incorporates a circuit which signals HIGH when another phone in parallel has been taken off-hook when the CYG2911 is off-hook. This feature is important for cable TV set-top boxes and direct broadcast satellite units which must hang-up (go on-hook) when a consumer needs the phone line to place a 911 or emergency call. The module is designed to meet FCC Part 68 requirements thus providing a low-risk design solution.
