OJ-EMDCH

Overview

The Taitien OJ-EMDCH is a programmable crystal oscillator (XO) designed for high-frequency clock signal generation. It operates within a frequency range of 15 MHz to 700 MHz and utilizes HCSL output logic. The device supports a 3.3V supply voltage and includes enable/disable functionality. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring stable timing solutions.

Feature Summary

• Programmable frequency generation capability
• HCSL output interface for noise immunity
• Integrated enable and disable control

Applications

• High-speed digital system clocking
• Telecommunications equipment timing
• Network infrastructure synchronization

Procurement Notes

Verify the specific frequency configuration and output load requirements against your design specifications before ordering. Ensure the 3.3V supply rail matches the datasheet recommendations. Confirm the 4-SMD no-lead footprint dimensions align with your PCB layout constraints to prevent assembly issues.

Selection Notes

Select this component when HCSL signaling is required for reduced jitter in high-frequency applications up to 700 MHz. Consider the programmability feature if multiple frequency variants are needed from a single part number. Evaluate the 3.3V power consumption against low-power alternatives if energy efficiency is a primary constraint.

Part Context

This model belongs to Taitien's FASTXO series, which focuses on low power and wide temperature range performance. It complements other variants like the OJ-EMDCL (LVPECL) and OJ-EMDCM (CML), offering different output logic options while maintaining similar form factors and programmable capabilities for flexible system design.

Replacement Considerations

Direct substitutes include Taitien OJ-EMDCL for LVPECL outputs or OJ-EMDCM for CML outputs. Verify that the replacement maintains the same 4-SMD package and 3.3V operation. Cross-check frequency ranges and enable pin configurations to ensure functional compatibility.
