Silicon Labs LVCMOS Clock (<4 outputs) SL16020DC

Silicon Labs' highly flexible, factory and I2C programmable LVCMOS clock generators can be customized to generate multiple frequencies with 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, programmable skew and spread spectrum.
SL15100/300/303 clocks generate frequencies from 3 to 200 MHz in configurations that support 2 to 4 LVCMOS outputs. A simple integer output divider is integrated so that integer-related outputs can be easily generated. To minimize EMI, AC parameters like rise/fall time can be customized.

Features:

• Low power: 2.1 mA typ at 38 MHz, CL=0 and VDD=3.3 V
• On-chip, programmable crystal capacitive load (CL): 8 to 20 pF
• 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' programmable spread spectrum clock generators feature a wide range of programming options that allow system designers to minimize electro-magnetic interference (EMI) at the application level.
