CXD2837ER

PROPRIETARY INFORMATION

The Sony CXD2837ERis a combined

DVB-T2 (incl.T2-Lite), DVB-T and DVB-C demodulator
CXD2837ER conforms to the ETSI EN 302-755 V1.3.1 (DVB-T2/T2-Lite), ETSI EN 300-
744 V1.6.1 (DVB-T) and ETSI EN 300-429 V1.2.1 (DVB-C) standards.

CXD2837ER offers class-leading performance, optimised BOM requiring no external

memory and low processor overhead.
