Silicon Labs Differential + LVCMOS Clock Generator Si5334C

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)

Silicon Labs' highly flexible, factory and I²C programmable and factory customizable LVCMOS clock generators can be customized to generate multiple independent non-integer-related frequencies with equivalent frequency synthesis capability of 8 PLLs, with exact frequency synthesis (0 ppm error), at significantly lower jitter, lower power and smaller size than competing solutions. Factory customized options are available to minimize EMI, including programmable edge rates, programmable impedance and programmable skew.
