SC14CVMDECT SF Cordless Voice Module
© 2012 Dialog Semiconductor B.V. 12 July 1, 2014 v1.6
.
Table 3 provides the overview of required and availa-
ble interfaces for a basic or a feature rich cordless FP
with the SC14CVMDECT SF.
.
Note 5: AFE setting is configurable, refer to document [1].
3.6 VOICE COMMUNICATION
An FP supports up to 6 registered PPs, where 4 of
these PPs can be in a call at the same time. Multiple
simultaneous calls are supported. Supported voice
codec is G.726 (32 kbit/s ADPCM) and G.722 (64 kbit/s
ADPCM). See Figure 5.
3.7 LIGHT DATA APPLICATION
The SC14CVMDECT SF supports Low Data Rate
(LDR) transmission up to 1.6 kbit/s with IWU to IWU
messaging. The LDR can be used in combination with
voice communication. See Figure 5.
3.8 LU10 DATA APPLICATION
The SC14CVMDECT SF supports CAT-iq LU10 data
transmission up to 54 kbit/s. Since LU10 data commu-
nication uses the B-Field it cannot be used in combina-
tion with voice communication. See Figure 6.
