2) Application Circuit for FM-1 and FM-2 Modes
Select either 16-bit [YCbCr] or RGB output as the output interface.
Number of field memories utilized
16-bit [YCbCr]: Use 2 field memories.
RGB: Use 3 field memories.
Video input can be five composite inputs or two S-Video inputs.
Connect unused video input pins to AGND. If a composite signal is input, the C input side
(video amp, A/D converter, etc.) will be in the OFF operation state.
If the input is limited by the composite signal, connect VIN (5:6), VRT2, VRB2, AMPOUT2,
ADIN2, and CLPOUT2 pins to AGND. Externally attached components such as capacitors
may be removed.
Set the MODE[3:0] pins to the prescribed setting.
For the MF-1 mode setting, externally generate and supply control signals for the field
memory.
For the MF-2 mode setting, memory control signals from M[7:4] can be supplied to the field
memory.
For the MF-2 mode setting, the output timing for HSYNC_L, VSYNC_L, ODD, VVALID, and
HVALID becomes the memory read timing. Data output from memory is aligned with the
variout sync signal timings. (See page 24 and page 25)
Supply power and GND for analog, A/D, and digital circuits on the circuit board should be
separated at the power source wherever possible. Power and GND lines for analog and A/D
circuits must be wide and low impedance.
