Si5365 P R E L I M I N A R Y D A TA S H E E T PIN-PROGRAMMABLE PRECISION CLOCK MULTIPLIER Description Features 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. The input clock frequency and clock multiplication ratio are selectable from a table of popular SONET, Ethernet, and Fibre Channel rates. The Si5365 is based on Silicon Laboratories' 3rdgeneration DSPLL® technology, which provides anyrate frequency 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 or 2.5 V supply, the Si5365 is ideal for providing clock multiplication in high performance timing applications. „ Selectable output frequencies ranging from 19.44 to 1050 MHz Low jitter clock outputs w/jitter generation as low as 0.6 ps rms (50 kHz–80 MHz) Integrated loop filter with selectable loop bandwidth (30 kHz to 1.3 MHz) Four clock inputs w/manual or automatically controlled hitless switching Five clock outputs with selectable signal format (LVPECL, LVDS, CML, CMOS) Support for ITU G.709 FEC ratios (255/238, 255/237, 255/236) LOS alarm outputs Digitally-controlled output phase adjust Pin-programmable settings On-chip voltage regulator for 1.8 or 2.5 V ±10% operation Small size: 14 x 14 mm 100-pin TQFP Pb-free, RoHS compliant „ „ „ „ „ „ „ „ „ „ „ Applications SONET/SDH OC-48/OC-192 line cards „ GbE/10GbE, 1/2/4/8/10GFC line cards „ ITU G.709 line cards „ Test and measurement „ CKIN1 ÷ N31 CKIN2 ÷ N32 ÷ NC1 CKOUT1 ÷ NC2 CKOUT2 ÷ NC3 CKOUT3 ® CKIN3 CKIN4 ÷ N33 DSPLL ÷ N34 ÷ N2 Divider Select Manual/Auto Switch ÷ NC4 CKOUT4 ÷ NC5 CKOUT5 Clock Select LOS/FOS Alarms Frequency Select Control Bandwidth Select VDD (1.8 or 2.5 V) GND Preliminary Rev. 0.34 3/07 Copyright © 2007 by Silicon Laboratories Si5365 This information applies to a product under development.

Figure 2. Si5365 Typical Application Circuit Preliminary Rev. 0.34 5 Si5365 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 multiplication in SONET and datacom applications, the Si5365 supports SONET-to-datacom frequency translations. Silicon Laboratories offers a PCbased software utility, DSPLLsim, 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 Silicon Laboratories' 3rdgeneration DSPLL® technology, which provides anyrate 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 via the BWSEL[1:0] pins and supports a range from 30 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. 6 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 output 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.

Silicon Laboratories has developed a PC-based software utility called DSPLLsim to simplify device configuration, including frequency planning and loop bandwidth selection.
