SI5335A-B02436-GM

SI5335A-B02436-GM is a Silicon Labs clock generator/jitter cleaner. It takes a single reference clock and produces multiple, phase‑coherent output clocks, using internal fractional‑N PLLs to synthesize the frequencies. Outputs can be configured for different signaling standards (CMOS/LVDS/LVPECL per output). It is programmed over I2C (SMBus-compatible) and supports features like jitter reduction, spread-spectrum clocking, and programmable power-down/output enable. The -GM suffix denotes a specific RoHS‑compliant packaging/lot variant; B02436 is a manufacturing code for that part. Typical applications include FPGA and processor timing, memory interfaces, SERDES, and telecom/data-communications boards requiring multiple synchronized clocks.
