Microchip Technology SY75707 LVCMOS Clock Buffer
Microchip Technology SY75707 LVCMOS Clock Buffer is a low-power differential-input to dual-output clock buffer and voltage-level translator. The SY75707 is designed with ultra-low additive jitter and support for HCSL, LVPECL, and LVDS differential inputs. Two LVCMOS outputs with built-in 50Ω series resistance can drive standard 50Ω transmission lines without external series resistors.
The Microchip SY75707 Clock Buffer accepts a 1.8V to 3.3V input supply and translates signals to a 1.2V to 1.8V output supply domain. The device supports frequencies up to 250MHz and remains transparent to spread-spectrum clock signals. The SY75707 has a compact 8-pin VDFN package, low power, and extended-temperature operation, making it well-suited for clock distribution, green servers, battery-powered equipment, and other space-constrained designs.
