Clock Buffer
Clock Buffer

Montage Technology’s M88TB(S)xxxxx series clock buffer chips leverage extensive expertise in high-speed analog technology to deliver stable and efficient clock distribution solutions for systems. This product series includes more than 20 part numbers and can be paired with Montage's clock generator products, offering customers comprehensive one-stop clock tree support.

The M88TB(S)xxxxx series features exceptionally low phase noise jitter performance, supports 2 to 3 reference clock inputs with frequencies up to 3.1 GHz, and certain models enable multi-channel asynchronous or synchronous glitch-free switching. The series can support up to 10 outputs, each of which can be flexibly configured for output type (e.g., LVPECL, LVDS, LVCMOS, LP-HCSL) and enable status. With a wide operating voltage range, the core and output groups can be independently powered between 1.5 V and 3.3 V. The series also boasts excellent Power Supply Rejection Ratio (PSRR) and enhanced Electrostatic Discharge (ESD) protection, enabling it to withstand harsh working environments while fully meeting the high flexibility and reliability requirements of various systems for clock trees.
