DESCRIPTION
The M52797 is AV switch semiconductor integrated circuit with
I2C bus control .
This IC contains 1-channel of 4-input audio switches and 1channel of 4-input video switches. Each audio switches and
video switches 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 ( M52797SP ) ; and SOP with a lead pitch of 1.27mm
( M52797FP ) .
