Description
The Si5335 is a highly flexible clock generator capable of synthesizing four completely non-integer-related frequencies up to 350 MHz. The device has four banks of outputs with each bank supporting one differential pair or two single-ended outputs. Using Silicon Laboratories patented MultiSynth fractional divider technology, all outputs are guaranteed to have 0 ppm frequency synthesis error regardless of configuration, enabling the replacement of multiple clock ICs and crystal oscillators with a single device.
Features
◾ Low power MultiSynth™ technology
enables independent, any-frequency
synthesis of four frequencies
◾ Configurable as a clock generator or
clock buffer device
◾ Three independent, user-assignable,
pin-selectable device configurations
◾ Highly-configurable output drivers with
up to four differential outputs, eight
single-ended clock outputs, or a
combination of both
◾ Low phase jitter of 0.7 ps RMS
◾ Flexible input reference:
• External crystal: 25 or 27 MHz
• CMOS input: 10 to 200 MHz
• SSTL/HSTL input: 10 to 350 MHz
• Differential input: 10 to 350 MHz
◾ Independently configurable outputs
support any frequency or format:
• LVPECL/LVDS/CML: 1 to 350 MHz
• HCSL: 1 to 250 MHz
• CMOS: 1 to 200 MHz
• SSTL/HSTL: 1 to 350 MHz
◾ Independent output voltage per driver:
1.5, 1.8, 2.5, or 3.3 V
◾ Single supply core with excellent
PSRR: 1.8, 2.5, 3.3 V
◾ Up to five user-assignable pin
functions simplify system design:
SSENB (spread spectrum control),
RESET, Master OEB or OEB per pin,
and Frequency plan select
(FS1, FS0)
◾ Loss of signal alarm
◾ PCIe Gen 1/2/3/4 common clock
compliant
◾ PCIe Gen 3 SRNS Compliant
◾ Two selectable loop bandwidth
settings: 1.6 MHz or 475 kHz
◾ Easy to customize with web-based
utility
◾ Small size: 4 x 4 mm, 24-QFN
◾ Low power (core):
• 45 mA (PLL mode)
• 12 mA (Buffer mode)
◾ Wide temperature range: –40 to
+85 °C
Applications
◾ Ethernet switch/router
◾ PCI Express Gen 1/2/3/4
◾ PCIe jitter attenuation
◾ DSL jitter attenuation
◾ Broadcast video/audio timing
◾ Processor and FPGA clocking
◾ MSAN/DSLAM/PON
◾ Fibre Channel, SAN
◾ Telecom line cards
◾ 1 GbE and 10 GbE
