Product data sheet Rev. 03 — 16 December 2008 3 of 56 NXP Semiconductors TDA9885; TDA9886 I2C-bus controlled multistandard alignment-free IF-PLL demodulators [1] Values of video and sound parameters can be decreased at VP = 4.5 V. [2] The sound carrier trap can be bypassed by switching the I2C-bus. In this way the full composite video spectrum appears at pin CVBS. The amplitude is 1.1 V (p-p). [3] Condition: luminance range (5 steps) from 0 % to 100 %. [4] AC load; CL < 20 pF and RL >1kΩ. The sound carrier frequencies (depending on TV standard) are attenuated by the integrated sound carrier traps (see Figure 15 to Figure 20; H (s) is the absolute value of transfer function). [5] S/N is the ratio of black-to-white amplitude to the noise voltage (RMS value measured on pin CVBS and tested at video black level, ‘quiet line’). Noise analyzer settings: B = 5 MHz, 200 kHz high-pass and sound carrier trap on. In case of S/NW weighted in accordance with “ITU-T J.61”. Measurements taken for B/G standard. [6] The intercarrier output signal at pin SIOMAD can be calculated by the following formula taking into account the internal video signal with 1.1 V (p-p) as a reference: and , where: is the correction term for RMS value, is the sound-to-picture carrier ratio at pins VIF1 and VIF2 in dB, 6 dB is the correction term of internal circuitry and ±3 dB is the tolerance of video output and intercarrier output Vo(intc)(rms).
