Title:
AN E1 INTERFACE WITH ELECTROMAGNETIC COMPATIBILITY CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2007/022693
Kind Code:
A1
Abstract:
An E1 interface with electromagnetic compatibility circuit includes E1 interface chip
(100), clampers (201,202,203,204), and over-voltage protectors (601,603), beads
(301,302,303,304) for noise suppression, matching networks (401,403), and
common mode transformers (501,503) integrated common mode inductor. The secondary
guard circuit made of clampers (201,202,203,204) and over-voltage protectors
(601,603) suppresses the surge, the beads (301,302,303,304) suppress the noise,
and the common mode transformers (501,503) integrated common mode inductor
not only can filter the common mode noise from the signal, but also can save the
space.
