SE111-00
SET-TOP VIDEO POST FILTER
The SE111-00 is a surface mountable active hybrid module designed to interface a digital video encoder
to 75Ω composite (CMPS), Luma (Y) and Chroma (C) outputs. Use of high performance operational
amplifiers ensures minimal differential phase/gain errors and the ability to drive ± 2.5V into 75Ω loads.
Other features
• Drives two composite outputs and one Y/C output
• accurate factory set gain of 0 dB (6 dB optional - order SE111-60)
• 75Ω output termination resistors provided
• sinx/x correction for 27 MHz sampling
• high input impedance - makes interfacing easy
• DC coupling eliminates tilt problems associated with AC coupling
• DC offset of encoder output (due to single rail operation) is corrected to bring blanking level near zero
• 24-pin j-lead package
