SI5338B-B02128-GM Description

Short technical summary and product information.

The Skyworks Solutions SI5338B-B02128-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.

With 0 ppm precision, each output clock is independently configurable for various signal formats and supply voltages. The device supports a wide range of input references, including external crystals, CMOS, SSTL/HSTL, and differential inputs. Output frequencies range from 0.16 MHz up to 710 MHz depending on the format (LVPECL/LVDS, HCSL, CMOS, SSTL/HSTL).

The SI5338B-B02128-GM operates from a 1.8, 2.5, or 3.3 V core supply and is programmable via an I2C/SMBus-compatible serial interface. It offers features like independent phase adjustment, configurable spread spectrum, and loss of lock/signal alarms. The device is housed in a compact 4x4 mm 24-QFN package, making it suitable for space-constrained applications.

Key applications include Ethernet switches/routers and PCIe Gen1/2/3/4 systems. The device operates over a wide temperature range of -40 to +85 °C.
