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. The input clock frequency and clock multiplication ratio are selectable from a table of popular SONET, Ethernet, and Fibre Channel frequencies. The Si5365 is based on Silicon Laboratories' 3rd-generation DSPLL® technology, which provides anyfrequency synthesis in a highly integrated PLL solution that eliminates the need for external VCXO and loop filter components. The DSPLL loop bandwidth is digitally programmable, providing jitter performance optimization at the application level. Operating from a single 1.8, 2.5, or 3.3 V supply, the Si5365 is ideal for providing clock multiplication in high performance timing applications.

Further Documentation The Si5365 is a low jitter, precision clock multiplier for high-speed communication systems, including SONET OC-48/OC-192, SDH STM-16/STM-64, 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 frequencies. In addition to providing clock multiplication in SONET and datacom applications, the Si5365 supports SONET-to-datacom frequency translations. Silicon Laboratories offers a PC-based software utility, DSPLLsim, that can be used to look up valid Si5365 frequency translations. This utility can be downloaded from http://www.silabs.com/timing (click on Documentation). Consult the Silicon Laboratories Any-Frequency Precision Clock Family Reference Manual (FRM) for detailed information about the Si5365. Additional design support is available from Silicon Laboratories through your distributor. Silicon Laboratories has developed a PC-based software utility called DSPLLsim to simplify device configuration, including frequency planning and loop bandwidth selection. The FRM and this utility can be downloaded from http://www.silabs.com/timing; click on Documentation. The Si5365 is based on Silicon Laboratories' 3rdgeneration DSPLL® technology, which provides anyfrequency 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 via the BWSEL[1:0] pins and supports a range from 150 kHz to 1.3 MHz. The DSPLLsim software utility can be used to calculate valid loop bandwidth settings for a given input clock frequency/clock multiplication 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. For system-level debugging, a bypass mode is available which drives the output clock directly from the input clock, bypassing the internal DSPLL. The device is powered by a single 1.8, 2.5, or 3.3 V supply.
