描述 Description

I2C BUS-COMPATIBLE US MTS PROCESSING LSIThe 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
