CDCLVP111HFG/EM

Overview

The CDCLVP111HFG/EM is a low-voltage, 1:10 LVPECL clock driver with selectable inputs, designed for high-speed clock distribution. It accepts differential LVPECL, LVECL, LVDS, CML, or SSTL inputs and distributes them to ten differential LVPECL outputs. The device supports a supply voltage range of 2.375 V to 3.8 V and operates from -55°C to 125°C. Key electrical parameters include a maximum frequency of 3.5 GHz, typical output skew of 15 ps, additive jitter less than 1 ps, and propagation delay under 355 ps. It is housed in a 36-pin Ceramic Flat Pack (CFP) package.

Feature Summary

• Distributes one differential clock input pair to ten differential LVPECL outputs with minimum skew.
• Supports selectable clock inputs via CLK_SEL pin for two independent sources.
• Compatible with LVPECL, LVECL, LVDS, CML, and SSTL input standards.
• Characterized for military temperature range (-55°C to 125°C) with controlled baseline.

Applications

• High-performance clock distribution systems
• Driving 50-ohm transmission lines
• Defense, aerospace, and medical applications

Procurement Notes

Verify that the /EM suffix indicates engineering evaluation samples intended for evaluation only. These units are processed to a non-compliant flow without burn-in and are tested at 25°C only. They are not suitable for qualification, production, radiation testing, or flight use, and do not carry performance warranties over the full MIL specified temperature range.

Selection Notes

Select this component for applications requiring low-additive jitter (<1 ps) and low-output skew (typical 15 ps) in harsh environments. Ensure the design accommodates the 36-pin CFP package dimensions. Verify power supply decoupling requirements, as the device is sensitive to noise on the power supply which can increase additive jitter.

Part Context

This part belongs to the CDCLVP111-SP family, which is characterized for extended temperature ranges and offers product traceability. The HFG suffix denotes the 36-pin Ceramic Flat Pack package. The /EM suffix specifically identifies the unit as an engineering evaluation sample, distinct from standard production units.

Replacement Considerations

Standard production equivalents include CDCLVP111SPHFG. For non-military applications, consider CDCLVP111VFR or CDCLVP111MVFREP, noting differences in operating temperature range and packaging.
