Composite Analog Video Signal – NTSC for Studio Applications
The SMPTE 253M standard defines a GBR component set with positive going signals and a maximum peak
level of 700 mV from blanking level. The green signal has a negative-going sync pulse of amplitude 300 mV
from blanking level. The dc offset, as defined by the blanking level of the signal, is 0.0 V
±
1.0 V. Figure 12 shows
the waveform of the green channel, onto which the horizontal sync is inserted.

Figure 12. SMPTE 253M Line Waveform (green channel)
For this mode, the INS3_INT control should be kept low to enable sync-on-green only and the device is put in
GBR 4:4:4 mode. This corresponds to the GBR with sync-on-green operation mode of Table 1.
Table 8 lists the THS8134 output currents that will produce compliant signals to this standard after proper
termination, together with the required input signals.
