Eval-ADV7195/96A/97RevC provides 96pin input port over which pixel data level accepted ADV7195/96A/97. Otherwise pixel data input over headers P4,P5,P6 input data must level. There additional evaluation board available from Analog Devices specifically designed interface Eval-ADV7195/96A/97RevC which converts data level. This converter board interfaces 96-pin input port. different clock source that provided pixel data EAV/SAV input mode required, ADV7195/96A/97 27Mhz oscillator (Y1) Progressive Scan Mode. HDTV Mode must exchanged with 74.25MHz 74.1758MHz oscillator. ADV7195/96A contains internal which
synchronizes 27MHz operation with operation Progressive Scan Mode. on-board push-button provides control over RESET pin. When RESET (PB1) pressed internal registers ADV7195/96A/97 reset default register settings internal counters reset. Eval-ADV7195/96A/97RevC also features external Voltage Reference (U4) which provides 1.235V Output Voltage.Alternatively internal Vref used changing settings jumper outputs buffer circuit.The analog component signals finally output over connectors. testpoints available monitor signals (TP1) (TP2). Eval-ADV7195/96A/97RevC fitted with ADuC812 Microconverter. ADuC812 optional required make full Eval-ADV7195/96A/97RevC board.
