Description
Encoder Phase
Phase difference of the main to encoded burst is sampled and applied
to the capacitor connected to this pin to shift the phase of the
re–encoded chrominance to match the main.
Encoder ACC
The Encoder ACC pin provides access to the internal chroma
reference sample and hold circuit, which stores the sampled value of
the main channel chroma burst amplitude on this external ACC
capacitor. The ACC amplifier matches the chroma amplitude of the
insert picture to that of the main picture.
Encoder PLL
Connection for Encoder PLL filter. See separate discussion for filter
values.
Encoder Crystal
4X Sub–Carrier crystal used to synchronize the encoding of the PIP
YUV from the field memory with the main video. The output from this
PLL is phase corrected to match the PIP video signal to the main video
at the PIP switch.
The crystal frequency is 14.31818 MHz.
Video Out
The selected Video 1/2 input is available at the Video Out mixed with
the PIP overlay when selected. This signal is a nominal 2.0 V
peak–to–peak signal unterminated. This connection is intended to
drive an external series 75 Ω load into a 75 Ω termination to ground to
provide a 1.0 Vpp signal at the termination.
Pins 11 to 13, 16 to 27, 55 and 56 are test pins configured as outputs in a high impedance state. In an application, no connection should be made to these pins.
