DATA SHEET

BIPOLAR ANALOG INTEGRATED CIRCUIT

µPC1851B

I²C BUS-COMPATIBLE US MTS PROCESSING LSI

The µPC1851B is an integrated circuit for US MTS (Multiplexed 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 µPC1851B allows users to switch modes, control volume and tone, and adjust the separation circuit

through the I²C bus.

FEATURES

• Stereo demodulation, SAP (Sub Audio Program) demodulation, dbx noise reduction decoding, I²C bus interface,

input selector (2 channels), surround processor (1 phase), volume and tone control circuits incorporated on a single

chip

• Mode switching, volume and tone control, and separation adjustment 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)

APPLICATION

• TV sets and VCRs for north America
