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
