SI5338A-B01952-GM

The Skyworks Solutions SI5338A-B01952-GM is a high-performance, low-jitter clock generator featuring patented MultiSynth™ technology. This device can synthesize any frequency on each of its four output drivers, allowing it to replace multiple crystal oscillators or function as a frequency translator.

Key electrical specifications include a low phase jitter of 0.7 ps RMS and true zero ppm frequency accuracy on all outputs. The device supports flexible input references ranging from 8 MHz to 710 MHz depending on the interface type. Output frequencies can be configured independently for various formats like LVPECL/LVDS (0.16 to 710 MHz), HCSL (0.16 to 250 MHz), CMOS (0.16 to 200 MHz), and SSTL/HSTL (0.16 to 350 MHz).

It operates from a 1.8, 2.5, or 3.3 V core supply and offers independent output voltage configuration per driver (1.5, 1.8, 2.5, or 3.3 V). The SI5338A-B01952-GM includes features like configurable spread spectrum, independent phase adjustment, and loss of lock/signal alarms. It is programmable via an I2C/SMBus-compatible serial interface.

Packaged in a compact 4x4 mm 24-QFN (exposed pad) with surface mount capability, this clock generator is suitable for space-constrained applications. It operates within a wide temperature range of -40 to +85 °C and consumes approximately 45 mA of core supply current.
