Si5332 Any-Frequency Clock Generators
Industry’s Most Highly Integrated Clock Generator for 10/25/100G
The Si5332 Any-Frequency clock generator provides the highest level of integration available, enabling complete clock tree consolidation in 10/25/100G data center, communications, and industrial applications. With an output frequency range of up to 333.33 MHz, the device features jitter performance of 175fs TYP, low power consumption (<300mA for 8 outputs), and is offered in 6/8/12-output options. Si5332 features our proprietary MultiSynth divider technology, providing fractional clock synthesis with 0ppm accuracy on any output. The device also includes an optional embedded reference crystal and up to 7 user defined hardware input pins that can be assigned as output enable for one or more outputs, frequency control, spread spectrum enablement, or input reference selection. A new multi-profile feature provides the ability to store up to 16 unique configuration files in the same orderable part number, using hardware input pins to select between each configuration. Si5332 can be quickly and easily configured using ClockBuilder Pro software, available in both factory pre-programmed as well as in-system programming options.

Maximize Jitter Performance Without Sacrificing Power
156.25MHz Output Clock Phase Jitter of 175fs RMS
Si5332 jitter performance is optimized to meet reference clock requirements in 10/25/100G data center, communications, and industrial markets. Integrated on-chip noise regulation eliminates the need for external LDOs and passive networks, providing added immunity to board and power supply noise to reduce effects on output clock jitter performance.
Achieving low jitter often comes at the sacrifice of high current consumption. Si5332 breaks that barrier, attaining current consumption levels 50% lower than competing solutions to help meet system current consumption budgets in energy friendly applications.
Ultimate Programming Flexibility
Users can create customized configuration files exactly matching system clock requirements in just minutes using the ClockBuilder Pro software utility. The device features up to 7 user definable hardware input pins that can be assigned to multiple different functions, including output enable for one or more outputs, frequency control, spread spectrum enablement, or input reference frequency selection. The multi-profile feature provides the ability to store up to 16 unique configuration files in the same orderable part number, using the hardware input pins to select between each configuration. Once a configuration file is complete, a part number can be generated instantly, with samples available in less than 2 weeks.
The Si5332 also features an I2C serial interface providing full in-system programmability.
