SI5369A-C-GQ

Clock Generators, PLLs, Frequency Synthesizers Overview

The SI5369A-C-GQ is a jitter-attenuating precision clock multiplier utilizing third-generation DSPLL technology. It accepts four clock inputs from 2 kHz to 710 MHz and generates five outputs ranging from 2 kHz to 945 MHz, with select frequencies reaching 1.4 GHz. The device operates on a single 1.8 V, 2.5 V, or 3.3 V supply within an ambient temperature range of -40°C to +85°C. It features digitally programmable loop bandwidth (4 Hz to 525 Hz) and supports I2C or SPI interfaces for configuration.
