The SAA7113H offers four analog signal inputs, two analog main channels with source
switch, clamp circuit, analog amplifier, anti-alias filter and video 9-bit CMOS ADC
(see
The anti-alias filters are adapted to the line-locked clock frequency via a filter control
circuit. The characteristics are shown in
and clamping control are frozen.

For board design without boundary scan implementation connect the TRST pin to ground.
This pin provides easy initialization of the Boundary Scan Test (BST) circuit. TRST can be used to force the
Test Access Port (TAP) controller to the TEST_LOGIC_RESET state (normal operation) at once.
In accordance with the IEEE1149.1 standard the pads TCK, TDI, TMS and TRST are input pads with an
internal pull-up transistor and TDO is a 3-state output pad.
