Preliminary specification
Multimedia radio tuner
OM5604; OM5606
FEATURES
Local/DX switching to improve large signal handling on
FM when an outdoor antenna or cable network is
connected
Local/DX function provides different search levels which
are useful for spectrum analyser functions
Three extra I/O expander ports are available for general
purpose (I
2
C-bus only)
RDS-MPX signal available
The module meets the
"FCC regulations"
The OM5604; OM5606 is in accordance with
"CENELEC EN55022" and "CENELEC EN50082-1".
GENERAL DESCRIPTION
The OM5604; OM5606 is an FM-radio tuner which
includes a brand new concept in tuning techniques. The
new tuning concept combines the advantages of hand
tuning together with electronic facilities and features. The
tuner is I
2
C-bus controlled.
ANTENNA CONNECTOR
RF connector
OM5604: F-connector (FM input impedance = 75
)
OM5606: IEC-connector (FM input impedance = 75
).
