Differential + LVCMOS Clock Generator -- Si5334B

Silicon Labs’ programmable clock generator IC solutions provide any rate, any output frequency synthesis. All combinations of output frequencies can be generated exactly with 0 ppm error.

The SL28PCIe10/30/50 devices are highly integrated clock generators capable of generating PCIe compliant differential clocks, standard frequency LVCMOS system clocks and user programmable clocks. This family is based on a platform that can be factory customized to provide a mix of HCSL and LVCMOS outputs. These outputs can be programmed to produce frequencies that range from 1 to 400 MHz, with programmable AC parameters (output drive strength, rise/fall times and differential signal cross point), spread spectrum support and programmable output impedance to prevent EMI issues.

Features:

• Factory customizable or I²C programmable
• Up to 6 HCSL and 5 LVCMOS outputs
• Spread spectrum clock generation
• Down or center spread, spread percentage: 01. to 5%
• Spread modulation frequency from 16 to 128 kHz
• User-definable control pins: power down, output enable, spread enable or frequency select, spread select
• 7 drive strength (programmable tr/tf) options
• Custom solutions available (contact Silicon Labs)
