PRACTICAL 601 FILTERS YUV ANTIALISING In many 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 a filter meeting the full requirements of Rec. ITU-R BT. 601-5 should be specified but cost may be prohibitive. Practical 601 filters allow a small compromise in performance resulting in significant cost savings which may be acceptable. • Choice of package format to suit requirement • Tight passband ripple specification Filter type Passband Shape Impedance (ohms) Sampling Frequency Insertion loss at 100 kHz End of Passband Amplitude ripple (dB) wrt 100 kHz • Flat and Sinx/x versions • Aqueously washable versions available Luminance Pre Flat 75 13.50 MHz < 1.5 dB 5.50 MHz < 0.05 to 5.25 MHz < 0.10 to 5.50 MHz 550 ± 5 ns < 6 ns to 5.50 MHz > 12 dB Luminance Post Sinx/x 75 13.50 MHz < 4.5 dB 5.50 MHz < 0.05 to 5.25 MHz < 0.101 to 5.50 MHz 556 ± 5 ns < 6 ns to 5.50 MHz > 12 dB 1 1 Chrominance Pre Flat 75 6.75 MHz Chrominance Post Sinx/x 75 6.75 MHz < 4.5 dB 2.2 MHz 40 dB FL597 Type number DR00024B package Type number DR00003A package FL400 FL470 FL423 FL471 1 2 Measured against sinx/x roll-off for a sampling frequency of 13.5 MHz.
