ANTIALIASING AND RECONSTRUCTION FILTERS TFT RANGE YUV COMPONENT SAMPLING These very small, low cost filters are intended for use with A-D and D-A video converters where some deviation from full ITU-R BT601 standard can be tolerated, ie single pass applications. These filters are designed for use in 4:2:2 sampling systems, ie 13.5 MHz for the luminance (Y) channel and 6.75 MHz for the chrominance (U and V) channels. • Ideal for single pass or monitor outputs • Choice of package format to suit requirement • Small size • Excellent pulse characteristics Type Number TFT1350F TFT1350S TFT0675F TFT0675S Impedance (ohms) 75 75 75 75 Filter Shape Passband Shape Lowpass Flat Lowpass Sinx/x Lowpass Flat Lowpass Sinx/x Sampling Frequency 13.50 MHz 13.50 MHz 6.75 MHz 6.75 MHz Insertion loss at 100 kHz End of Passband < 1.5 dB 5.5 MHz < 4.5 dB 5.5 MHz < 1.5 dB 2.2 MHz < 3.0 dB 2.2 MHz Amplitude ripple < 0.2 dB < 0.3 dB1 < 0.2 dB < 0.3 dB2 Delay time at 200 kHz Group delay ripple 287 ns < 15 ns 306 ns < 15 ns 430 ns < 30 ns 417 ns < 30 ns Group delay equalised bandwidth > 5.0 MHz > 5.0 MHz > 2.2 MHz > 2.2 MHz Attenuation at 1/2 S.F. 12 ± 2 dB 12 ± 2 dB 12 ± 2 dB 12 ± 2 dB 8.00 MHz 8.00 MHz 4.20 MHz 4.20 MHz > 40 dB < 0.5% 40 dB nominal < 4% 40 dB nominal < 4% wrt loss at 100 kHz Start of stopband Stopband attenuation > 40 dB Kp-rating - 2T sinesquared pulse < 0.5% T=100 ns Aqueous Washable Yes Yes Yes Yes Package size DR00008B DR00008B DR00005A DR00008B 1 Measured against sinx/x roll-off for a sampling frequency of 13.5 MHz.
