The MAX9320B is a low-skew, 1-to-2 differential driver designed for clock and data distribution. It features ultra-low propagation delay, part-to-part skew, and output-to-output skew, making it ideal for clock distribution. The device operates over a +3.0V to +5.5V supply range for PECL/LVPECL operation, and a -3.0V to -5.5V supply range for ECL/LVECL operation. The MAX9320B is offered in industry-standard 8-pin TSSOP and SO packages.
The MAX9320B is a low‑skew, 1‑to‑2 differential driver intended for clock and data distribution. It accepts differential PECL/LVPECL inputs over a +3.0 V to +5.5 V supply, or differential ECL/LVECL inputs over a –3.0 V to –5.5 V supply, and reproduces the input on two differential outputs. Typical applications include precision clock distribution, low‑jitter data repeaters, and protection switching.
Key electrical characteristics include an ultra‑low propagation delay of 208 ps, part‑to‑part skew of 20 ps, output‑to‑output skew of 6 ps, and a maximum supply current of 30 mA. The device is offered in 8‑pin TSSOP and SO packages and operates from –40 °C to +85 °C. Recommended layout practices such as 50 Ω trace impedance and proper output termination are also described.
