DESCRIPTION

tv_out2

TV analog output S-VIDEO

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).

tv_vref

Reference output voltage from internal

A decoupling capacitor (CBG) needs to be connected for optimum

bandgap

performance.

tv_vfb1

Amplifier feedback node

Amplifier feedback node. An external resistor is connected between

this node and tv_out1. The nominal value of ROUT1 is 1650

Ω (1%).

tv_vfb2

Amplifier feedback node

Amplifier feedback node. An external resistor is connected between

this node and tv_out2. The nominal value of ROUT2 is 1650

Ω (1%).
