CDCLVP111VF

Overview

The CDCLVP111VF is a low-skew clock buffer manufactured by Texas Instruments, designed for high-performance clock distribution. It features a 2:10 fanout ratio, accepting differential inputs and providing ten differential LVPECL outputs. The device supports input signals including CML, LVDS, LVPECL, and SSTL, with a maximum operating frequency of 3.5 GHz. It operates on a supply voltage range of 2.375 V to 3.8 V and is housed in a 32-LQFP package (7x7 mm). The component functions as both a fanout buffer and a multiplexer, suitable for driving 50-Ω transmission lines.

Feature Summary

• 2:10 Fanout Ratio: Distributes one differential clock input pair to ten differential LVPECL output pairs.
• Wide Input Compatibility: Supports CML, LVDS, LVPECL, and SSTL input signal types.
• High Frequency Operation: Capable of processing clock frequencies up to 3.5 GHz.
• Low Skew Design: Engineered for minimum skew applications to maintain signal integrity in clock distribution networks.

Applications

• High-performance clock distribution systems requiring low jitter and skew.
• Driving 50-Ω transmission lines in digital communication equipment.
• Multiplexing multiple clock sources into a single distribution network.
• Fanout buffering for LVPECL-compatible logic families.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's datasheet to confirm package type and reel/tray configuration. Ensure the selected variant matches the required operating temperature range and supply voltage specifications for the target application environment.

Selection Notes

Select this component when a 2:10 LVPECL fanout buffer with selectable input multiplexing is required. Confirm that the system power supply falls within the 2.375 V to 3.8 V range. Verify that the PCB layout accommodates the 32-LQFP (7x7 mm) footprint and that the input signal levels are compatible with CML, LVDS, or SSTL standards.

Part Context

The CDCLVP111VF belongs to the CDCLVP111 series of low-skew clock drivers from Texas Instruments. This series is optimized for distributing differential clock signals with minimal propagation delay and skew. The VF suffix indicates the 32-LQFP package variant, distinguishing it from other package options like QFN available in the same family.

Replacement Considerations

Check for pin-to-pin compatible alternatives such as MC100EP111, ES6111, LVEP111, or PTN1111 if form-factor compatibility is critical. Verify electrical parameters including supply voltage and output drive strength before substitution.
