Description
ZL30255LFG7 is a high‑performance, programmable clock generator/jitter cleaner from the ZL timing family. It takes a reference clock and produces multiple low‑jitter, phase‑aligned output clocks suitable for telecom and data‑communications gear. Typical capabilities include fractional‑N PLL synthesis, jitter attenuation, holdover, multiple output formats (e.g., LVDS/CMOS/PECL), and a serial control interface (I2C/SPI) for configuration. The LFG7 suffix denotes a specific package variant. Common applications are network timing, SONET/SDH, synchronous Ethernet, backplane timing, and other systems requiring precise, synchronized clocks from a single reference. For exact specs—output frequencies, jitter figures, input references, and programming—consult the official datasheet.
