SI5386A-E-GMR

The Skyworks Solutions SI5386A-E-GMR is an advanced 12-channel clock multiplier and jitter attenuator, leveraging Skyworks' 4th generation DSPLL technology. This IC is engineered for demanding wireless infrastructure applications, including eCPRI RRHs, BBUs, and small cells, where high integration and superior phase noise performance are critical.

Key features include the ability to generate any combination of output frequencies from any input frequency, with differential input frequency ranges from 7.68 MHz to 750 MHz and LVCMOS up to 250 MHz. The device offers differential output frequencies up to 2.94912 GHz (integer) and up to 735 MHz (fractional), with LVCMOS outputs up to 250 MHz. It boasts ultra-low RMS jitter of 72 fs (12 kHz–20 MHz) and phase noise of -118 dBc/Hz @ 100Hz offset on a 122.88MHz carrier.

The SI5386A-E-GMR operates over a temperature range of -40°C to 85°C and is housed in a 64-VFQFN exposed pad package, suitable for surface mounting. Its all-digital solution provides high immunity to external board disturbances and eliminates the need for external loop filter components, simplifying design and improving reliability.

This component is ITU-T G.8262 compliant and supports various output types including CML, HCSL, LVCMOS, LVDS, and LVPECL. The flexible timing capabilities make it ideal for generating diverse clock sets required for eCPRI-based systems, such as ADC/DAC clocks, RF LOs, and Ethernet clocks from a single IC.
