3-Input 1-Output Video Switch (with Y-C mix) MM1188

* * Note : 1 2 Measurement of IN1-C and IN1-Y mixed differential gain and differential phase is as follows.

Switch status : S1=3, S2=1, S3=S4=S5=S6=2

Measuring procedure : Input a 1.0VP-P staircase wave signal (without chroma signal) to SG1,

and a chroma signal to SG2. Measure TP3 differential gain and differential phase.
