Analogue Filter Start of Stopband 21.0 MHz Analogue Filter Stopband rejection 35 dB Analogue Filter Group delay ripple < 3 ns to 3.58 MHz < 16 ns to 6.0 MHz Differential gain 1.5% typical Differential phase 1.5 ° typical Supply current + 300 mA +5v 20 mA -5v Digital Filter details ADC-100, ADC-101, ADC-110, ADC-111, ADC-120, ADC-121 ADC-122 Filter Type TMC2242A TMC2242C Passband ± 0.01 dB to 0.22 fs ± 0.014 dB to 0.22 fs Attenuation at 0.25 fs - 6 dB - 6 dB Stopband attenuation > 59 dB from 0.28 fs > 56 dB from 0.29 fs Data latency 34 clk periods 68 clk periods Note: The ADC-122R uses the TMC2242C digital filter which features a double delay mode enabling the luminance module (fs = 27 MHz) to output data synchronously with the colour difference modules (fs = 13.5 MHz). This eliminates the need for a digital delay of the luminance data by 34 clock cycles. For further information consult Fairchild datasheet TMC2242C. An absolute delay difference of 37 ns exists between the ADC-122R and ADC-121R due to the differences in the analogue filters. |
