Silicon Labs Integrated Clock + VCXO Solution SL38160-18AH

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.

The SL38000 series of clock generators offer both VCXO and spread spectrum clock generation (SSCG) options, with LVCMOS outputs from 1-200 MHz.

Features:

• Integrated VCXO functionality with 150 ppm pull range
• 4-PLL architecture capable of generating up to 11 LVCMOS outputs
• Programmable/configurable output frequencies from 1 to 200 MHz
• 8 to 48 MHz external crystals supported
• 8 to 166 MHz external clock input supported
• Customizable PD#/OE/SSON#/FS functions
• Customizable/programmable rise/fall times (7 settings per output)
• Programmable/configurable center or down spread spectrum with up to 16 dB of EMI reduction
• Spread spectrum modulation from 0.25 to 5.0% with both linear and non-linear profiles
• Programmable/configurable crystal load capacitors (CL=10 to 20 pF)
• Low noise PLL by-pass mode for reference clock generation
• 4 independent output supply pins (VDDO)
• I²C control interface
• Packages: 28-pin TSSOP
• 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.
