SI4706 Datasheet, PDF (13/15 Pages) List of Unclassifed Manufacturers – Introducing High-Performance FM RDS Data Receiver ICs

Si4706/49 Unmatched Programmability
Feature
Benefit
 Interrupts on change in  RDS block A almost never changes and block B
block A and / or block B changes with programming content. Interrupts likely
indicate change or similarity in broadcaster or content
 Full granularity with all
blocks and BLER
 Allows host processor to post-process if user desires
 User can also select interrupts by BLER level,
conserving host processor cycles
 Interrupts by block-
specific BLER
 Allows error-thresholds, content-specific or
application-specific interrupts to save host power
 On-chip buffer up to 25
RDS groups with
associated BLER by
block (100 blocks)
 Reduces interrupts and therefore power consumption
load of host processor
 Especially useful in decoding ODA information with
large groups of data
 Greater than 50 times more data than competition
provides
