TDA9897; TDA9898
Multistandard hybrid IF processing
Synthesizer reference either via 4 MHz crystal or via an external source. Individual pins
for crystal and external reference allows optimum interface denition and supports use of
custom reference frequency offset.
8.10 I2C-bus transceiver and slave address
Four different I2C-bus device addresses to enable application with multi-IC use.
I2C-bus transceiver input ports can handle three different I2C-bus voltages.
Read-out functions as TDA9887 plus additional read out of VIF AGC and TAGC status.
