CYG2100/CYG21 10/CYG2120
DESCRIPTION
Clare’s CYG21XX Series DAA modules provide a
complete telephone line interface circuit in a small
1.07" x 1.07" x 0.4" package. The modules provide a
fast and cost effective solution for designs that
require an interface to the telephone line. The
CYG2100 is designed to meet PTT and safety
regulations in 13 countries.
The CYG21 10 and CYG2120 are designed to meet PTT
regulations in France and Spain, respectively.
