Description
The Si5334 is a high performance, low jitter clock generator capable of synthesizing any frequency on each of the devices four differential output clocks. The device accepts an external reference clock or crystal and generates four differential clock outputs, each of which is independently configurable to any frequency up to 350 MHz and select frequencies to 710 MHz.
Features
◾ Low-power MultiSynth technology
enables independent, any-frequency
synthesis on four differential output
drivers
◾ Highly-configurable output drivers
support up to four differential outputs
or eight single-ended clock outputs or
a combination of both
◾ Low phase jitter: 0.7 ps RMS typ
◾ High-precision synthesis allows true
0 ppm frequency accuracy on all
outputs
◾ Flexible input reference
• External crystal: 8 to 30 MHz
• CMOS input: 5 to 200 MHz
• SSTL/HSTL input: 5 to 350 MHz
• Differential input: 5 to 710 MHz
◾ Independently-configurable outputs
support any frequency or format
• LVPECL/LVDS: 0.16 to 710 MHz
• HCSL: 0.16 to 250 MHz
• CMOS: 0.16 to 200 MHz
• SSTL/HSTL: 0.16 to 350 MHz
◾ Independent output voltage per driver
• 1.5, 1.8, 2.5, or 3.3 V
◾ Independent core supply voltage
• 1.8, 2.5, or 3.3 V
◾ Frequency increment/decrement
feature enables glitchless frequency
adjustments in 1 ppm steps
◾ Phase adjustment on each of the
output drivers with <20 ps steps
◾ SSC on any or all outputs that is
compliant to PCI Express
◾ Optional external feedback mode
allows zero-delay implementation
◾ Loss-of-lock and loss-of-signal alarm
◾ Simple pin control
◾ Small size: 4x4 mm, 24-QFN
◾ Low power: 45 mA core supply typ
◾ Wide temperature range:
–40 to +85 °C
◾ Contact Silicon Labs for custom
versions
