UG397: Si5332-6A-EVB Users' Guide
(Using Si5332-AM1-QFN32-EVB)
The Si5332-6A-EVB is used for evaluating the six-output Automotive Grade Si5332
Low Jitter Any-Frequency Clock Generator. The Si5332-AM1 device uses the pa-
tented Multisynth™ technology to generate up to six independent clock frequencies
each with 0 ppm synthesis error. The Si5332-6A-EVB has two independent input
reference clocks or can use the on-board 25 MHz crystal as reference. The
Si5332-6A-EVB can be controlled and configured using the Silicon Labs Clock
Builder Pro™ (CBPro™) software tool.
KEY FEATURES
• Powered from either USB port or external +5V
power supply.
• 25 MHz crystal reference or external input clock
reference.
• Programmable device VDD supply for operation
at 3.3 V, 2.5 V, or 1.8 V, controlled by CBPro™
Software.
• Programmable VDDO supplies allow each of
the 6 outputs to have its own power supply
voltage selectable from 3.3 V, 2.5 V, 1.8 V, or
1.5 V (1.5 V LVCMOS only).
• CBPro™ GUI-controlled voltage, current, and
power measurements of VDD and all VDDO
supplies.
• SMA connectors for all input and output clocks.
• External digital input functions emulated via on-
board switches.
