Product Description:
The SI5351B is an I2C-programmable any-frequency CMOS clock generator with a built-in VCXO. It is designed to replace crystals, crystal oscillators, VCXOs, phase-locked loops (PLLs), and fanout buffers in cost-sensitive applications. The device can generate any frequency up to 200 MHz on each of its outputs with 0 ppm error.

Key Features:

• Generates up to eight non-integer-related frequencies from 2.5 kHz to 200 MHz
• I2C user definable configuration
• Exact frequency synthesis at each output (0 ppm error)
• Highly linear VCXO
• Optional clock input (CLKIN)
• Low output period jitter: < 70 ps pp, typical
• Configurable spread spectrum selectable at each output
• Operates from a 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 for level translation
• Excellent PSRR eliminates external power supply filtering
• Very low power consumption
• Adjustable output delay
• Available in three package types:
• PCIE Gen 1 compatible
• Supports HCSL compatible swing

Package Type:

• 20-QFN (4x4 mm) package, which provides 8 outputs.
