AD1970 Product details

GENERAL DESCRIPTION
The AD1970 is a complete analog or digital-in, analog-out BTSC encoder which includes pilot-tone generation and subcarrier mixing functions. The stereo ADC provides the means for digitization of the analog baseband audio signal. A built-in high performance DAC is provided to output the BTSC baseband composite signal. The output of the AD1970 can be connected with minimal external circuitry to the input of a 4.5 MHz aural FM modulator.

    Complete BTSC encoder
    Pilot tone generator
    Includes subcarrier modulation
    Channel separation: 30 dB
    Bandwidth up to 14 kHz
    Stereo analog or digital input
    Phat-Stereo™ algorithm for stereo image enhancement
    Dialog enhancement function for playing wide dynamic
        range video sources over built-in TV speakers
    Includes L − R dual-band compressor
    I2C port for control of modes, effects, and parameters
    Analog input performance
        74 dB dynamic range
        −72 dB THD + N
    Digital input performance
        87 dB dynamic range
        −83 dB THD + N
    Integrated op amps for analog inputs and outputs
    Single-ended output reduces external part count
    Integrated PLL generates all clocks from composite video,
        48 kHz sample clock, or high speed master clock
    Sync stripper to recover video clock from composite
        video signal
    Output level control for setting aural carrier deviation
    Macrovision™-compliant
    Dolby™ RF mode-compatible
    48-pin LQFP plastic package

APPLICATIONS
    Digital set top box
