Si5383/84 Reference Manual
Overview
This Reference Manual is intended to provide system, PCB design, signal integrity,
and software engineers the necessary technical information to successfully use the
Si5383/84 devices in end applications. The official device specifications can be found in
the Si5383/84 data sheet.
The Si5383/84 combines the industry's smallest footprint and lowest power network
synchronizer clock with unmatched frequency synthesis flexibility and ultra-low jitter.
The three independent DSPLLs are individually configurable as a SyncE PLL or a gener-
al-purpose PLL for processor/FPGA clocking, and support digitally controlled oscillator
(DCO) mode for IEEE 1588 (PTP) clock steering applications. In addition, locking to
a 1 pps input frequency is available on DSPLL D. The DCO mode provides precise
timing adjustment to 1 part per trillion (ppt). The Si5383/84 can also be used in legacy
SETS systems needing Stratum 3/3E compliance. The unique design of the Si5383/84
allows the device to accept a TCXO/OCXO with any frequency, and the reference clock
jitter does not degrade output performance. The Si5383/84 is configurable via a serial
interface with in-circuit programmable non-volatile memory so it always powers up into
a known configuration. Programming the Si5383/84 is easy with ClockBuilder Pro soft-
ware. Factory pre-programmed devices are also available.

  • Page 6: Overview

    The Si5383/84 is well suited for both traditional and packet-based network timing solutions. The Si5383/84 contains three independent DSPLLs allowing for flexible single-chip timing architecture solutions. The Si5383 contains a single DSPLL D that can be configured for 1PPS applications to lock to a 1 Hz input, requiring no additional external circuitry. Each DSPLL contains a digitally controlled oscillator (DCO) for precise timing for IEEE 1588 (PTP) clock steering applications.

  • Page 7: Functional Description

    The Si5383/84 takes advantage of Skyworks' fourth-generation DSPLL technology to offer the industry’s most integrated and flexible jitter attenuating clock generator solution. The Si5383 offers three DSPLLs and the Si5384 offers one DSPLL. Each of the DSPLLs operate independently from each other and are controlled through a common serial interface. DSPLLs (A, C, and D) all have access to any of the three inputs (IN0 to IN2), after having been divided down by the input P dividers, which are either fractional or integer.

    The hex file provided from CBPro should be parsed out into separate “records” that will be sent one record at a time from the I2C master to the Si5383/84. This format is similar to that used by the Intel Hex file. The most important thing is to make sure the correct I2C Address is used.

    4.4.1 Free Run Mode Once power is applied to the Si5383/84 and initialization is complete, all three DSPLLs will automatically enter freerun mode, generat- ing the frequencies determined by the NVM. The frequency accuracy and stability of the generated output clocks in freerun mode is entirely dependent on the reference clock (REF/REFb), while the external crystal at the XA/XB pins determines the jitter performance of the output clocks.

    Output 5 of the Si5383/84 can be configured to generate a 1PPS clock. This is done by cascading the R5 and R6 dividers, done internal to the Si5383/84 as shown in the figure below, and easily set when using CBPro. Output 6 is still usable in this case but is limited to a frequency of 33.5 MHz or less.

  • Page 45: Performance Guidelines For Outputs

    The jitter generation of the Si5383/84 is so low that crosstalk can become a significant portion of the final measured output jitter. Some of the crosstalk will come from the Si5383/84, and some will be introduced by the PCB.

There is essentially no jitter attenuation from the XA/XB pins to the output clocks and ony the best XOs will avoid a jitter penalty compared to using an approved crystal.
