range is 0-0.75 VPP, and may require an attenuator to reduce the input amplitude to the
desired level. If not used, connect to AGND via a 0.1-F capacitor (see Figure 6-1).

Digital Section
Active video indicator output. This signal is high during the horizontal active time of the

video AVID output. AVID toggling during vertical blanking intervals is controlled by bit 2 of
the active video cropping start pixel LSB register at address 12h (see Section 3.21.17).

Digital supply. Connect to 1.8-V digital supply.
FID: Odd/even field indicator or vertical lock indicator. For the odd/even indicator, a 1
indicates the odd field.
FID/GLCO

O
GLCO: This serial output carries color PLL information. A slave device can decode the
information to allow chrominance frequency control from the TVP5150AM1 decoder. Data is
transmitted at the SCLK rate in Genlock mode. In RTC mode, SCLK/4 is used.
HSYNC

O
Horizontal synchronization signal
INTREQ: Interrupt request output
GPCL/VBLK: General-purpose control logic. This terminal has two functions:

via I2C.
VBLK: Vertical blank output. In this mode the GPCL terminal indicates the vertical
blanking interval of the output video. The beginning and end times of this signal are
programmable via I2C.
