Description
The Si5350A is a user-definable custom clock generator that is ideally suited for
replacing crystals and crystal oscillators in cost-sensitive applications. Based on
a PLL + high resolution fractional divider MultiSynthTM architecture, the Si5350A
can generate any frequency up to 125 MHz on each of its outputs with 0 ppm
error. Spread spectrum is selectable (on/off) on any of the outputs. Custom pin-
controlled Si5350A devices can be requested using the ClockBuilder web-based
part number utility (www.silabs.com/ClockBuilder).
Functional Block Diagram
Generates up to 8 non-integer
frequencies from 8 kHz to 125 MHz
Exact frequency synthesis at each
output (0 ppm error)
Glitchless frequency changes
Low output period jitter: 100 ps pp
Configurable Spread Spectrum
selectable at each output
User-configurable control pins:
Output Enable (OEB_0/1/2)
Power Down (PDN)
Frequency Select (FS_0/1)
Spread Spectrum Enable (SSEN)
Operates from a low-cost, fixed
frequency crystal: 25 or 27 MHz
Separate voltage supply pins:
Core VDD: 2.5 V or 3.3 V
Output VDDO: 2.5 V or 3.3 V
Excellent PSRR eliminates external
power supply filtering
Very low power consumption
(<15 mA)
Available in 3 packages types:
10-MSOP: 3 outputs
24-QSOP: 8 outputs
20-QFN (4x4 mm): 8 outputs
