MITSUMI 3-Input 2-Output 3-Circuit Video Switch MM1238 3-Input 2-Output 3-Circuit Video Switch Monolithic IC MM1238 Outline July 5, 1993 This IC is a video switch IC developed for high-end large/medium TVs incorporating three 3-input 2-output circuits. It is ideal for switching BS/JSB/CS or M-N converters (mute to NTSC conversion). The BS-CS decoder can be used as a W decoder. Features 1. One of the two video signal outputs is used for external output, and has a 6dB amp, 75Ω, 1VP-P 2. Input impedance 1~3 video circuits 15kΩ 1~3 audio circuits 68kΩ 3. Crosstalk Video -60dB (at 4.43MHz) Audio -80dB (at 1kHz) Video : Audio -70dB (at 100kHz) 4. Frequency response 10MHz (6dB, 75Ω, amp only, 7MHz) 5.
