SIT95148AI-A00000-Y Integrated Circuit Chip MEMS Network Synchronizer with Low Jitter 120 fs and 11-Output for IEEE 1588 Applications

SiT95148 is a single-chip MEMS network synchronizer optimized for IEEE 1588 and time synchronization applications. The device comes with 4 independent time domains, 1 mHz to 4 kHz programmable loop bandwidth, low wander mode and fastest hitless switching. Its low noise quad-PLL architecture and programmable output drivers provide up to 10 differential or 20 LVCMOS low jitter clock outputs. It supports 4 additional clock inputs with Frac-N dividers, enabling virtually any input to output frequency translation configurations from 8 kHz to 2.1 GHz.

• Clock-system-on-a-chip with integrated MEMS, simplifies designs
• No crystal capacity matching, always-accurate frequency synthesis
• No noise coupling onto crystal circuits, guaranteed jitter
• Resistant to vibration and board bending, anywhere PCB replacement
• Flexible features for best IEEE 1588, syncE, and timing synchronization performance
• 4 inputs, 11 outputs, 4 PLLs, up to 2.1 GHz output frequency for flexible frequency translation
• Individually configurable output types and voltage to support a wide range of processor and SOCs
• Programmable loop bandwidth (1 mHz to 4 kHz)
• Low wander mode using precision TCXO for clock recovery and OCXO for holdover
• Fastest hitless switching (sub 50 ps phase build-out)
• 35% space saving ideal for high density designs
• 9 x 9 mm package, no external XTAL/oscillator required
