Трёхканальный ЦАП ADV7125JSTZ240 предназначен для формирования аналоговых видеосигналов RGB с тактовой частотой до 240 MSPS при питании 5 V.
Он содержит три согласованных 8-разрядных видеоканала с комплементарными токовыми выходами для работы на нагрузку 75 Ω.
Встроенный опорный источник 1.235 V и программируемый резистор RSET задают амплитуду полного видеосигнала.
TTL-совместимый цифровой интерфейс и сигналы BLANK/SYNC обеспечивают формирование стандартных уровней RS-343A/RS-170.
Микросхема выпускается в 48-выводном корпусе LQFP для коммерческого температурного диапазона.
