As part of continual product improvement the specifications, details and dimensions shown in this publication are subject to change without notice FARA008.DOC Page 1 of 2 Jun-99 (A) The Faraday FL952 is a reconstruction filter for use in oversampled systems using the Raytheon 22191/22091 and 22193 digital video encoder. It combines removal of clock frequency and sidebands in conjunction with the Raytheon digital filter, sinx/x correction and also pre-distortion of the amplitude response to compensate the roll off / ripple of the lower tap digital filter employed by the Raytheon.
- Low cost oversampled reconstruction filter. • Space saving SIL format.
- Excellent repeatability between filters. • Sinx/x correction.
- Digital filter roll off compensation.. Filter Shape Lowpass Passband Shape Sinx/x Sampling Frequency 27 MHz Insertion Loss at 100 kHz 2.95 dB + 0.1 dB End Of Passband 5.0 MHz Passband Amplitude Ripple < 0.2 dB 1 Passband Amplitude Match between filters < + 0.03 dB to 4.8 MHz < + 0.05 - 0.1 dB to 5.0 MHz Start Of Stopband > 20 MHz Stopband Attenuation wrt 100 kHz > 40 dB Group Delay Ripple < 10 ns Group Delay Bandwidth 5.0 MHz Insertion Group Delay at 200 kHz 30 ns + 10 ns Pulse And Bar K - Rating 0.5 % typ < 1% max. Crosstalk at 0.25” (6.35 mm) centres 0 to 5.0 MHz > 40 dB Impedance 75 ohms Temperature Range 0°C to 40°C 1 Measured against sinx/x pre-distortion curve for a sampling frequency of 27 MHz and frequency roll off of TMC22191/22091 and 22193 digital encoder.
