MAX9320/MAX9320A is a low-skew, 1-to-2 differential driver designed for clock and data distribution. The input is reproduced at two differential outputs. The differential input can be adapted to accept single-ended inputs by applying an external reference voltage. The MAX9320/MAX9320A feature ultra-low propagation delay (208ps), part-to-part skew (20ps), and output-to-output skew (6ps) with 30mA maximum supply current, making these devices ideal for clock distribution. For interfacing to differential HSTL and LVPECL signals, these devices operate over a +2.25V to +3.8V supply range, allowing high-performance clock or data distrib- ution in systems with a nominal +2.5V or +3.3V supply. For differential LVECL operation, these devices operate from a -2.25V to -3.8V supply. The pinout is the only difference between the MAX9320 and MAX9320A. Multiple pinouts are provided to simplify routing across a backplane to either side of a double-sided board. These devices are offered in space-saving 8-pin SOT23, µMAX, and SO packages. Applications include precision clock distribution, low-jitter data repeater and protection switching.
The MAX9320 and MAX9320A are differential drivers designed for high‑performance clock and data distribution. They accept differential inputs and can be adapted for single‑ended inputs using an external reference voltage. The devices operate from +2.25 V to +3.8 V for HSTL/LVPECL and from –2.25 V to –3.8 V for LVECL, making them suitable for a range of high‑speed signaling standards.
Key features include an ultra‑low typical propagation delay of 208 ps, part‑to‑part skew of 20 ps, output‑to‑output skew of 6 ps, and low supply current (typical 22 mA). The parts are offered in compact 8‑pin SOT23‑8, µMAX, and SO packages with exposed‑pad options for improved thermal performance.
