I/O
PAL line indicator or horizontal lock indicator (HLK).
For PAL line indicator, a 1 indicates a noninverted line, and a 0 indicates an inverted line.
For horizontal lock indicator, a 1 indicates the internal horizontal PLL is in a locked state, and a 0 indicates
the internal horizontal PLL is in an unlocked state.
This terminal is an input terminal during reset and is used in conjunction with GLCO and FID to select the
mode of the host interface (see Table 2
3).

Strapping Terminals Description
All of the following terminals have reset strapping options. The states of these terminals are sampled during reset
to configure the TVP5145 device for various modes of operation. These terminals are temporarily turned into inputs
during reset and return to their normal operation after reset. Each of the following terminals can be pulled up with a
10-k
resistor to set a 1 to the corresponding bit or be left undriven during reset. The AVID terminal has an internal
pulldown resistor (approximately 40 k
) to pull the terminal low to set a 0.
