Silicon Labs EMI Reduction Clock Si5351B-A-GM

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.

Configurable parameters to reduce EMI include a wide range of signal integrity adjustments like rise/fall times, output impedance, drive strength, programmable edge rates, programmable skew and spread spectrum percentage/modulation rate.

Features:

• Any frequency, any-bank frequencies from 1 MHz to 200 MHz
• Single input with 8 CMOS outputs organized into 4 banks
• Independent VDDO per output eliminates external level translators (1.8, 2.5, 3.3V)
• Low period jitter: 50 ps pk-pk
• Crystal (25 or 27 MHz) or clock (5-200MHz) input
• I²C programmable (Si5356) supports spread spectrum
• Si5356 in-system, flash-based programmable with small form factor MCU

Silicon Labs' highly-integrated clock + VCXO solutions feature an integrated voltage controlled oscillator (VCXO). Free-running and VCXO clocks can be generated by one device, making them ideal for cost-sensitive consumer applications.

Si5350/51 clock generators feature an integrated VCXO that does not require pullable crystals. These devices come in both 3 and 8 output configurations.

Features:

• Integrated high linearity VCXO
• Pullable crystal not required
• Generates any frequency on any output, 8 kHz to 133 MHz
• Exact clock synthesis: 0 ppm error
• Similar frequency flexibility as 8 independent PLLs
• Crystal or clock input
• <100 ps pk-pk period jitter for any configuration
• Glitchless switching between output frequencies
• I²C programmable or pin-controlled
• Excellent PSRR: no discrete components required
• Factory and field-progammable versions available
• Two-week sample lead time for any custom clock
