ITU-R BT. 601 FILTERS Appendix 2 – Part B YUV ANTIALISING – STANDARD FOOTPRINT Designed to meet the full requirements of Rec. ITU-R BT. 601-5 to suppress aliasing and to reconstruct signals in 4:2:2 YUV format A-D and D-A video interface applications operating at a sampling rate of 18.00 MHz for the luminance (Y) channel and 9.00 MHz for the Colour Difference (U and V) channels. • Fully compliant with ITU-R BT601 • Industry Standard Footprint • Aqueously washable • Tight passband ripple specification • Tighter delay time tolerances available • Flat and Sinx/x versions Type Number 601F0767 601S0767 601F0367 601S0367 Impedance (ohms) 75 75 75 75 Filter Shape Lowpass Lowpass Lowpass Lowpass Passband Shape Flat Sinx/x Flat Sinx/x Sampling Frequency 18.00 MHz 18.00 MHz 9.00 MHz 9.00 MHz Insertion loss at 100 kHz < 1.5 dB < 4.5 dB < 1.5 dB < 4.5 dB End of Passband 7.67 MHz 7.67 MHz 3.67 MHz 3.67 MHz <± 0.025 to 7.33 MHz <± 0.0501 to 7.67 MHz <± 0.050 to 3.67 MHz <± 0.0502 to 3.67 MHz wrt 100 kHz <± 0.025 to 7.33 MHz <± 0.050 to 7.67 MHz Delay time at 200 kHz 570 ± 6nS 568 ± 6nS 1115 ± 11 nS 1113 ± 11 nS Group delay ripple <±3nS to 7.67 MHz <±3 nS to 7.67 MHz > 12 dB > 12 dB <± 6 nS to 3.67 MHz <±12 nS to 4.0 MHz > 6 dB <± 6 nS to 3.67 MHz <± 12 nS to 4.0 MHz 2 > 6 dB Start of stopband 10.67 MHz 10.67 MHz 5.33 MHz 5.33 MHz Stopband attenuation > 40 dB > 40 dB > 40 dB > 40 dB DR00003A DR00003A DR00003A DR00003A Amplitude ripple (dB) 1 wrt delay at 200 kHz Attenuation at 1/2 S.F. 1 wrt loss at 100 kHz wrt loss at end of passband Package size 1 Measured against sinx/x roll-off for a sampling frequency of 18.00 MHz.
