si5365 6 preliminary rev. 0.34 1. functional description the si5365 is a low jitter, precision clock multiplier for high-speed communication systems, including sonet oc-48/oc-192, ethernet, and fibre channel, in which the application requires clock multiplication without jitter attenuation. the si5365 accepts four clock inputs ranging from 19.44 to 707 mhz and generates five frequency-multiplied clock outputs ranging from 19.44 to 1050 mhz. by default the four clock inputs are at the same frequency and the five clock outputs are at the same frequency. two of the output clocks can be divided down further to generate an integer sub-multiple frequency. the input clock frequency and clock multiplication ratio are selectable from a table of popular sonet, ethernet, and fibre channel rates. in addition to providing clock multiplic ation in sonet and datacom applications, the si5365 supports sonet-to-datacom frequency translations. silicon laboratories offers a pc- based software utility, dspll sim , that can be used to look up valid si5365 frequency translations. this utility can be downloaded from www.silabs.com/timing . this information is also available in the any-rate precision clock family reference manual, also available from www.silabs.com/timing . the si5365 is based on s ilicon laboratories' 3rd- generation dspll ? technology, which provides any- rate frequency synthesis in a highly integrated pll solution that eliminates the need for external vcxo and loop filter components. the si5365 pll loop bandwidth is digitally programmable vi a the bwsel[1:0] pins and supports a range from 30 khz to 1.3 mhz. the dspll sim software utility can be used to calculate valid loop bandwidth settings for a given input clock frequency/clock mu ltiplication ratio. the si5365 monitors all input clocks for loss-of-signal and provides a los alarm when it detects a missing clock. in the case when the input clocks enter alarm conditions, the pll will freeze the dco output frequency near its last value to maintain operation with an internal state close to the last valid operating state. the si5365 has five differential clock outputs. the signal format of the clock outputs is programmable to support lvpecl, lvds, cml, or cmos loads. if not required, unused clock outputs can be powered down to minimize power consumption. the phase difference between the selected input clock and the output clocks is adjustable in 200 ps increments for system skew control. for system-level debugging, a bypass mode is available which drives the outp ut clock directly from the input clock, bypassing the internal dspll. the device is powered by a single 1.8 or 2.5 v supply. 1.1. further documentation consult the silicon laborato ries any-rate precision clock family reference manual (frm) for more detailed information about the si5365. the frm can be downloaded from www.silabs.com/timing . silicon laboratories has developed a pc-based software utility called dspll sim to simplify device configuration, including frequency planning and loop bandwidth selection. this utility can be downloaded from www.silabs.com/timing .
