CJMCU Si5351B Clock Signal Generator Module I2C Programmable 27 MHz + VCXO
Si5351 is used for crystals, crystal oscillators, VCXOs, phase locked rings (PLLs) and a clock signal generator with an I2C protocol, ideal for switching fanout buffers. Based on a PLL/VCXO+ high-resolution MultiSynth fractional splitter architecture, the Si5351 can produce any frequency up to 160 MHz on each of its outputs with 0 ppm error.
Features:
- Generates 8 non-integer frequencies from 8 kHz to 160 MHz
- I2C user-defined configuration
- Full frequency synthesis (0 ppm) on each output error)
- Highly linear VCXO
- Optional clock input (CLKIN)
- Low output time jitter: 100 ps pp
- Configurable spread spectrum selectable
- Operates from low-cost, fixed frequency crystal: 25 or 27 MHz
- Supports static phase offset
- Programmable rise/fall time control
- Glitchless frequency changes
- Separate voltage supply pins:
- Core VDD: 2.5 or 3.3 V
- Output VDDO: 1.8, 2.5 or 3.3 V
- Excellent PSRR eliminates external power supply filtering
- Very low power consumption
- Adjustable output-to-output delay
- Available in 3 package types:
- 10-MSOP: 3 output
- 24-QSOP: 8 outputs
- 20-QFN (4x4 mm): 8 outputs
- PCIE Gen 1 compliant
- Supports HCSL compliant swing feature
