I/O DESCRIPTION
O TV analog output S-VIDEO
I Reference output voltage from internal
bandgap
O Amplifier feedback node
O Amplifier feedback node
DAC2 video output. An external resistor is connected between this
node and tv_vfb2. The nominal value of ROUT2 is 1650 Ω. Finally,
note that this is the output node that drives the load (75 Ω).
A decoupling capacitor (CBG) needs to be connected for optimum
performance.
Amplifier feedback node. An external resistor is connected between
this node and tv_out1. The nominal value of ROUT1 is 1650 Ω (1%).
