The MAX9242/MAX9244/MAX9246/MAX9254 deserialize three LVDS serial-data inputs into 21 single-ended LVC- MOS/LVTTL outputs. They feature spread-spectrum capability to reduce EMI by spreading the output data and clock frequency over a specified range.
The Maxim MAX9242/9244/9246/9254 family are 21‑bit deserializers that convert three LVDS serial‑data inputs into single‑ended LVC‑MOS/LVTTL outputs. They feature programmable spread‑spectrum (±2 % or ±4 % or off) and programmable DC‑balance, allowing operation in both DC‑balanced and non‑DC‑balanced modes. Output logic levels are selectable from 1.8 V to 5 V, and the MAX9254 version provides higher output drive for heavy capacitive loads.
The devices are offered in a 48‑pin TSSOP package, operate from –40 °C to +105 °C, and meet ISO 10605 and IEC 61000‑4‑2 ESD specifications. Detailed electrical characteristics, timing diagrams, and layout guidelines are provided for system designers.
