6 / 56 page 2003 Oct 02 6 Philips Semiconductors Product specification I2C-bus controlled single and multistandard alignment-free IF-PLL demodulators TDA9885; TDA9886 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: V 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). 7. Pin REF is able to operate as a 1-pin crystal oscillator input as well as an external reference signal input, e.g. from the tuning system. V o(intc)(rms) 1.1 1 22 ----------- × 10 r × = r 1 20 ------ V i(SC) V i(PC) -------------- dB () 6 dB 3 dB ± + × = 1 22 ----------- V iSC () V iPC () --------------- dB () |
