REYFA

The REYFA is designed as one kind of video oversampling SMD filter device that costs resulting from oversampling techniques. REYFA has good attenuation between the frequencies of Fs/4 and 3Fs/4 where Fs is the Master Clock rate, and in order to preserve the integrity of the signal, REYFA has a good amplitude and group delay characteristics in the passband, similar to the requirements of CCIR601 but due to the above considerations do not have significant attenuation below 21 MHz.

Features of the REYFA are:(1)Reflowable; (2)Washable; (3)Surface mount compatibility; (4)Small size, low cost; (5)Flat or Sinx/x versions; (6)Luminance and Chrominance versions.

The characteristics of the REYFA can be summarized as:(1)Impedance: 150 ;(2)Sinx/x correction: No;(3)Sampling Frequency: 27.0 MHz;(4)End of Passband: 5.75 MHz;(5)Amplifier ripple: < 0.12 dB;(6)G.D. ripple: < 6 ns;(7)Start of stopband: 21.5 MHz;(8)Stopband atten. wrt 100 kHz: > 40 dB;(9)Delay time nom. at 200 kHz: 30 ns;(10)Aqueous Washable: Yes.
