The DS90UR241/DS90UR124 is a 5-43MHz DC-balanced 24-bit LVDS serializer and deserializer. The device translates a 24-bit parallel bus into a fully transparent data/control LVDS serial stream with embedded clock information, eliminating the skew problems between parallel data and clock paths. It saves system cost by narrowing data paths, which in turn reduce PCB layers, cable width, and connector size and pins.
This handbook describes the DS90UR241 and DS90UR124 devices, which are 5‑43 MHz DC‑balanced 24‑bit LVDS serializers and deserializers. It includes general descriptions, absolute maximum ratings, electrical characteristics, and timing requirements for both the serializer and deserializer functions.
The document contains detailed specifications such as supply voltage, temperature range, package type, and current consumption, as well as timing diagrams, test circuits, and notes for designers. It is intended for engineers designing high‑speed LVDS interfaces using National Semiconductor components.
