MAX9378：Anything-to-LVPECL/LVDS Translators with Pin-Selectable Divide-by-Four

Industry's First 2.0GHz Anything-to-LVPECL/LVDS Divide-by-Four Translators

The MAX9377/MAX9378 are fully differential, high-speed, low-jitter anything-to-LVPECL and anything-to-LVDS translators, respectively, with a selectable divide-by-four function. Low propagation delay and high speed make them ideal for various high-speed network routing and backplane applications at speeds up to 2GHz in nondivide mode. The MAX9377/MAX9378 accept any differential input signal within the supply rails and with minimum amplitude of 100mV. Inputs are fully compatible with the LVDS, LVPECL, HSTL, and CML differential signaling standards. The MAX9377 outputs are LVPECL and have sufficient current to drive 50Ω transmission lines. The MAX9378 outputs are LVDS and conform to the ANSI EIA/TIA-644 LVDS standard. The MAX9377/MAX9378 are available in 8-pin µMAX packages and operate from a single +3.3V supply over the -40°C to +85°C temperature range.
