Si5345/44/42 Rev D Data Sheet

10-Channel, Any-Frequency, Any-Output Jitter Attenuator/

Clock Multiplier

KEY FEATURES

• Generates any combination of output

frequencies from any input frequency

These jitter attenuating clock multipliers combine fourth-generation DSPLL^™and

MultiSynth^™technologies to enable any-frequency clock generation and jitter attenu-

ation for applications requiring the highest level of jitter performance. These devices

are programmable via a serial interface with in-circuit programmable non-volatile

memory (NVM) so they always power up with a known frequency configuration. They

support free-run, synchronous, and holdover modes of operation, and offer both au-

tomatic and manual input clock switching. The loop filter is fully integrated on-chip,

eliminating the risk of noise coupling associated with discrete solutions. Furthermore,

the jitter attenuation bandwidth is digitally programmable, providing jitter perform-

ance optimization at the application level. Programming the Si5345/44/42 is easy

• Ultra-low jitter of 90 fs rms

• External Crystal: 25 to 54 MHz

• Input frequency range

• Differential: 8 kHz to 750 MHz

• LVCMOS: 8 kHz to 250 MHz

• Output frequency range

• Differential: 100 Hz to 1028 MHz

• LVCMOS: 100 Hz to 250 MHz

with Silicon Labs’ ClockBuilder Pro^™software. Factory preprogrammed devices are

also available.

• Meets G.8262 EEC Option 1, 2 (SyncE)

• Highly configurable outputs compatible with

LVDS, LVPECL, LVCMOS, CML, and HCSL

with programmable signal amplitude

Applications:

• Si5345: 4 input, 10 output, 64-QFN 9×9 mm

• Si5344: 4 input, 4 output, 44-QFN 7×7 mm

• Si5342: 4 input, 2 output, 44-QFN 7×7 mm

• OTN muxponders and transponders

• 10/40/100 G networking line cards

• GbE/10 GbE/100 GbE Synchronous Ethernet (ITU-T G.8262)

• Carrier Ethernet switches

• SONET/SDH line cards

• Broadcast video

• Test and measurement

• ITU-T G.8262 (SyncE) compliant
