The TDA9819 from Philips is a multistandard vision and sound-IF PLL integrated circuit with DVB-IF processing capabilities. Designed for robust performance, it operates with a 5V supply voltage and handles IF frequencies of 38.9 MHz and 45.75 MHz.
Key electrical specifications include a typical output CVBS signal voltage of 2V peak-to-peak and a -3 dB video bandwidth of 78MHz for M, B/G, and L standards. It offers a weighted signal-to-noise ratio for video of 60dB and intermodulation attenuation of 64dB at both 1.1 MHz and 3.3 MHz.
The device supports true synchronous demodulation with active carrier regeneration, providing linear demodulation and good intermodulation figures. It features a VCO frequency switchable between TV and DVB frequencies, a separate video amplifier for sound trap buffering, and VIF AGC detection. The TDA9819 is available in a 32-lead SOT-23 package, suitable for surface mounting.
This IC is applicable for IF frequencies of 38.9 MHz and 45.75 MHz, and includes DVB functions such as a gain-controlled IF-amplifier and a mixer for DVB-IF.
