Circuit-, IC descriptions and list of abbreviations
EN 126 DVDR615, MRV6409.
I2C controlled de-interlace uses a 64Mbit SDRAM (32bit x 2M)
to perform high quality de-interlacing (meshing). The de-
interlace gets its digital YUV input data from the PNX7100
(7400). The format of the digital YUV input to the Fli2301 is
CCIR656 with separated Hsync, Vsync, and odd/even signal
running on 27MHz.
9.6 Service UART Interface
Logic IC 74HCT14D (item 7111) is used to make a level
conversion from microprocessor (LVTTL) to +/-5V (compatible
with most RS232 interfaces) and vice versa. The control line
MPIO19_CTL_SERVICE is used to activate service and
diagnostic SW at start up procedure. The connectivity is
provided via an external service tool.
9.7 I/O Extension Board
This board feeds the internal S/PDIF signal from the Digital
board to an optical and/or digital out connector. For European
players, also an YUV output is present on this board.
