I2C BUS-COMPATIBLE US MTS PROCESSING LSI

The µPC1854A is an integrated circuit for US MTS (Multichannel Television Sound) system with the addition of the I2C bus interface. All functions required for US MTS system are incorporated on a single chip.

The µPC1854A allows users to switch modes and adjust filter and separation circuits through the I2C bus.

FEATURES

• Stereo demodulation, SAP (Sub Audio Program) demodulation, dbx noise reduction decoding, and I2C bus interface incorporated on a single chip

• Mode switching and filter/separation adjustments through the I2C bus

• Power supply: 8 V to 10 V

• On-chip input attenuator for simple interface with intermediate frequency processing IC (I2C bus control)

• Output level: 1.4 Vp-p (with L+R signals, 100 modulation)

APPLICATIONS

• TV sets and VCRs for north America
