Document Type and Number:
WIPO Patent Application WO/2012/006857
Kind Code:
A1
Abstract:
An integrated talkback chip and an integrated talkback system including the chip are disclosed. The integrated chip includes a CPU, a talkback processing part and a digital interface control part(4). The talkback processing part is used for performing talkback signal receiving and transmitting processes; the CPU is connected with the digital interface control part(4); and the digital interface control part(4) is connected with the talkback processing part. The CPU controls the working state and parameters of the talkback processing part via the digital interface control part(4). The CPU, the talkback processing part and the digital interface control part(4) are integrated in a chip by a digital signal technology and CMOS technology. The solutions are of high integration level and the cost of the complete machine is cheap, which not only solve the problems of the traditional analog interphone that the circuit construct is complex, there are a lot of separate elements and the cost is high, but also greatly improve the technique parameters and the stability of the product.
