The MAX9420–MAX9423 are extremely fast, low-skew quad LVECL-to-LVPECL translators designed for high-speed signal and clock driver applications. The devices feature ultra-low propagation delay and channel-to-channel skew. The four channels can be operated synchronously or asynchronously. They have negative and positive supply ranges, as well as various input and output termination options.
The MAX9420‑MAX9423 family are ultra‑fast, low‑skew quad LVECL‑to‑LVPECL translators designed for high‑speed signal and clock driver applications. They feature a typical propagation delay of 336 ps and a channel‑to‑channel skew of 17 ps. The four channels can be operated synchronously with an external clock or asynchronously via the SEL input, and an enable input can force all outputs to a differential low state.
The devices are supplied in 32‑pin 5 mm×5 mm TQFP and 32‑lead 5 mm×5 mm QFN packages. Pin configurations, electrical characteristics, and recommended PCB layout guidelines are detailed, along with power‑supply bypassing, output termination, and input biasing recommendations. Absolute maximum ratings, operating temperature range, and typical performance curves are also provided.
