ITU-R BT. 601 FILTERS Appendix 2 – Part A YUV ANTIALISING – SPACE SAVING 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 standard sampling rates of 13.5 MHz for the luminance (Y) channel and 6.75 MHz for the Colour Difference (U and V) channels. • Fully compliant with ITU-R BT601 • Choice of package format to suit requirement • Tighter delay time tolerances available • Tight passband ripple specification Type Number Impedance (ohms) Filter Shape Passband Shape Sampling Frequency Insertion loss at 100 kHz End of Passband Amplitude ripple (dB) wrt 100 kHz Delay time at 200 kHz Group delay ripple *601F0575 75 Lowpass Flat 13.50 MHz < 1.5 dB 5.75 MHz <± 0.025 to 5.50 MHz <± 0.050 to 5.75 MHz 760 ± 7nS <±3nS to 5.75 MHz *601S0575 75 Lowpass Sinx/x 13.50 MHz < 4.5 dB 5.75 MHz <± 0.0251 to 5.50 MHz <± 0.0501 to 5.75 MHz 758 ± 7nS <±3 nS to 5.75 MHz *601F0275 75 Lowpass Flat 6.75 MHz < 1.5 dB 2.75 MHz <± 0.050 to 2.75 MHz *601S0275 75 Lowpass Sinx/x 6.75 MHz < 4.5 dB 2.75 MHz <± 0.0502 to 2.75 MHz > 12 dB 1488 ± 14 nS <± 6 nS to 2.75 MHz <±12 nS to 3.0 MHz > 6 dB 1486 ± 14 nS <± 6 nS to 2.75 MHz <± 12 nS to 3.0 MHz 2 > 6 dB > 12 dB 8.00 MHz > 40 dB 8.00 MHz > 40 dB 4.00 MHz > 40 dB 4.00 MHz > 40 dB No No No No wrt delay at 200 kHz Attenuation at 1/2 S.F. 1 wrt loss at 100 kHz Start of stopband Stopband attenuation wrt loss at end of passband Aqueous Washable3 Order code Package size 601 - DR00023B - P - DR00026A - H Passband Edge MHz 0575 0275 Passband Shape F - Flat S - Sinx/x 1 Measured against sinx/x roll-off for a sampling frequency of 13.5 MHz.
