High Performance Clock Generators

The any-frequency, any-output Si5341/40 clock generators combine a wide-band PLL with proprietary MultiSynth fractional synthesizer technology to offer a versatile and high performance clock generator platform. This highly flexible architecture is capable of synthesizing a wide range of integer and non-integer related frequencies up to 1028 MHz on 10 differential clock outputs while delivering sub-100 fs rms phase jitter performance with 0 ppm error. Each of the clock outputs can be assigned its own format and output voltage enabling the Si5341/40 to replace multiple clock ICs and oscillators with a single device making it a true “clock tree on a chip”.



Features

  • Up to 10 independent clock outputs
  • MultiSynth technology delivers any frequency on any output
  • SPI or I2C programmable
  • Any format, any output: LVPECL, LVDS, HCSL, LVCMOS, HSTL, SSTL, and CML
  • Clockbuilder Pro simplifies configuration
  • Independent Output clock supply pins eliminate external level translator
  • Low phase jitter: < 100 fs
  • Si5341: 4-input, 10 output in 9 mm x 9 mm QFN64 (3.3, 2.5, 1.8 V)
  • Si5340: 4-input, 4 output in 7 mm x 7 mm QFN74
