The CS7123 is a three‑channel 10‑bit high‑speed VGA D/A converter with TTL input, internal reference, low power and up to 240 MHz operation.
The Chipsea CS7123 provides three independent 10‑bit DAC channels for VGA video applications. It accepts TTL video inputs, includes an internal voltage reference, and offers low‑power operation while supporting video sync and blanking signals.
The device is supplied in a 48‑lead LQFP package, features configurable output current (2 mA low / 26 mA high), and delivers SFDR of –70 dB at 1 MHz and –53 dB at 140 MHz. Typical applications include video graphics systems, digital video controllers, and high‑resolution display interfaces. This manual is written in Chinese.
