SI5344H-D-GM Description

Short technical summary and product information.

The Skyworks Solutions SI5344H-D-GM is a specialized jitter attenuating clock multiplier designed for high data rate coherent optical transceiver applications. It combines fourth-generation DSPLL with ultra-low phase jitter and MultiSynth technologies.

This device supports high-speed outputs generating ultra-low jitter up to 2.75 GHz in High-Frequency Mode, with typical phase jitter of 50 fs-rms (1 MHz-40 MHz). It also features MultiSynth Mode outputs capable of any frequency up to 717.5 MHz, with typical phase jitter of 150 fs-rms (12 kHz-20 MHz). The input frequency range is 8 kHz to 750 MHz.

Key electrical features include programmable jitter attenuation bandwidth, configurable outputs compatible with LVDS, LVPECL, LVCMOS, CML, and HCSL, and DCO mode with 0.001 ppb step control. It operates with core voltages of 1.8V and 3.3V, and independent output supply pins supporting 3.3V, 2.5V, or 1.8V.

The SI5344H-D-GM is available in a 44-QFN (7x7) package and is surface mountable. It operates within a temperature range of -40°C to +85°C. The device is programmable via a serial interface (I2C or SPI) with in-circuit programmable non-volatile memory (NVM).
