SL1400A

The SL1400A is designed as one member of the SL...A series which are general purpose video filters. This range of 7-pole Elliptical Function Low Pass Filters is intended for bandwidth limitation with minimal distortion of the transmitted signal. The filters SL1400A are corrected for Group Delay distortion over approx. 92% of the passband and for loss distortion over the entire passband. Degradation of a composite video signal is minimal when a 4.5 MHz or 5.5 MHz filter is selected for a 525 or 625 line T.V. system. Specifically the 14.0 MHz filter of SL1400A has become popular in COFDM systems to band limit 8.0 MHz signals centred on 9.143 MHz.

Some important electrical characteristics of SL1400A  are concluded into several points as follow. (1)Its end of passband would be 14MHz. (2)Its start of stopband would be 19.6MHz. (3)Its group delay ripple would be max 8ns. (4)Its delay time would be 115ns. And so on. This range of SL1400A may be extended down to 0.5 MHz and up to 20 MHz. Filters with other end of passband frequencies within the range can be supplied at no extra cost.

And also some other important data of SL1400A are concluded into sveral points as follow. (1)Impedance would be 75ohms. (2)Its insertion loss would have the maximum value of 1.5dB. (3)Its stopband attenuation wrt 100kHz would have the minimum value of 40dB. (4)Its amplitude ripple in passband would have the maximum value of 0.3dB. It should be noted that video performance for filters of 5.0MHz (4.5MHz for 525 line) and above. (5)Its pulse and bar: K-rating would have the maximum value of 1%. (6)Its luminance or chrominance gain inequality (20T) would have the maximum value of 3%. (7)Its luminance or chrominance delay inequality would have the maximum value of 10ns. (8)Its aqueous washable would be yes. (9)Its package would be DR00005A. And so on. At present we have not got so much information about this IC and we would try hard to get more information about SL1400A.
