of
output 0dB or 6dB .
Notice. This is not a final specification.
The M52790 is AV switch semiconductor integrated circuit with
I2C bus control .
This IC contains 2-channels of 4-input audio switches and 2channels of 4-input video switches. Each channel can be
controled independently .
The video switches contain amplifiers can be controled a gain
•Video and stereo sound switches in one package
•Wide frequency range ( video switch )...........DC~20MHz
•High separation ( video switch )
.................Crosstalk -60dB ( typ. ) at 1MHz
•Two types of packages are provided : SDIP with a lead pitch of
1.778mm ( M52790SP ) ; and SSOP with a lead pitch of 0.8mm
( M52790FP ) .
