DS4625P+100/100

Programmable Timers And Oscillators Overview

The DS4625P+100/100 is a dual-output, low-jitter clock oscillator manufactured by Analog Devices Inc./Maxim Integrated. It integrates an AT-cut crystal, oscillator, and low-noise phase-locked loop (PLL) within a 5.0mm x 3.2mm surface-mount LCCC package. The device generates two identical 100MHz LVPECL output pairs. It operates from a single +3.3V ±10% supply with an operating temperature range of -40°C to +85°C. Key electrical characteristics include typical integrated phase jitter of less than 0.7ps RMS (measured from 12kHz to 20MHz), initial frequency tolerance of ±20ppm at +25°C, and total frequency stability of ±50ppm over the full operating range.

Programmable Timers And Oscillators Feature Summary

• Dual LVPECL outputs providing identical 100MHz signals
• Integrated AT-cut crystal and low-noise PLL for low jitter performance (<0.7ps RMS typical)
• +3.3V ±10% single supply operation with active-high OE pin control
• 5.0mm x 3.2mm ceramic LCCC package with exposed pad for thermal relief

Programmable Timers And Oscillators Applications

• XGMII Clock Oscillator
• InfiniBand applications
• SAS/SATA interfaces
• PCIe systems
• 1GbE/10GbE networking equipment

Programmable Timers And Oscillators Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status via the lead finish specification (JESD97 category e4). Ensure proper handling procedures are followed due to moisture sensitivity and the requirement for ground connection on the exposed thermal pad during assembly.

Programmable Timers And Oscillators Selection Notes

Select this model when identical 100MHz LVPECL clocks are required for both output pairs. Verify that the system design supports the specific 5.0mm x 3.2mm LCCC footprint and requires termination resistors connected to PECL_BIAS at VCC - 2.0V. Consider alternative frequencies if different clock rates are needed for the primary or secondary outputs.

Programmable Timers And Oscillators Part Context

This part belongs to the DS4625 family of 3.3V dual-output LVPECL clock oscillators. Other variants in the series offer different standard frequency combinations such as 125MHz, 150MHz, 156.25MHz, and 200MHz. The 'P+' suffix indicates a lead-free/RoHS-compliant package with gold over nickel lead finish.

Programmable Timers And Oscillators Replacement Considerations

Direct replacements within the same package and functionality include DS4625P+125/125, DS4625P+150/150, and DS4625P+156.25/156.25. Custom frequency options require contacting the factory directly.
