The SAA7102; SAA7103 can be directly connected to a PC video graphics controller with
a maximum resolution of 800 × 600 at a 50 Hz or 60 Hz frame rate. A programmable
scaler scales the computer graphics picture so that it will fit into a standard TV screen with
an adjustable underscan area. Non-interlaced-to-interlaced conversion is optimized with
an adjustable anti-flicker filter for a flicker-free display at a very high sharpness.
Besides the most common 16-bit 4 : 2 : 2 C
edge clocking), other C

A complete 3 × 256 bytes Look-Up Table (LUT), which can be used, for example, as a
separate gamma corrector, is located in the RGB domain; it can be loaded either through
the video input port Pixel Data (PD) or via the I
The SAA7102; SAA7103 supports a 32-bit × 32-bit × 2-bit hardware cursor, the pattern of
which can also be loaded through the video input port or via the I
It is also possible to encode interlaced 4 : 2 : 2 video signals such as PC-DVD; for that the
anti-flicker filter, and in most cases the scaler, will simply be bypassed.

Pin type: I = input, O = output, S = supply.
In accordance with the “IEEE1149.1” standard the pins TDI, TMS, TCK and TRST are input pins with an
internal pull-up resistor and TDO is a 3-state output pin.
Pins FSVGC, VSVGC, CBO, HSVGC and TTXRQ_XCLKO2 are used for bootstrapping; see
For board design without boundary scan implementation connect TRST to ground.
This pin provides easy initialization of the BST circuit. TRST can be used to force the Test Access Port
(TAP) controller to the TEST_LOGIC_RESET state (normal operation) at once.
