SN65LVEL11DGKR

Clock Buffers, Drivers Overview

The SN65LVEL11DGKR is a low-voltage PECL clock buffer manufactured by Texas Instruments. It provides a 1:2 fanout configuration, converting a single differential input into two differential outputs. The device operates within a supply voltage range of 3.0 V to 3.6 V and supports data rates up to 3.8 GHz. It features low skew characteristics suitable for high-speed timing applications. The component is housed in an 8-pin VSSOP package with a junction temperature range of -40°C to +85°C. The 'R' suffix indicates reel packaging.

Clock Buffers, Drivers Feature Summary

• 1:2 Differential Fanout Buffer
• Supports LVPECL signaling standards
• Maximum frequency of 3.8 GHz
• Low skew performance for precise timing

Clock Buffers, Drivers Applications

• High-speed clock distribution networks
• PECL signal buffering and fanout
• Telecommunications equipment requiring low jitter
• Test and measurement instrumentation

Clock Buffers, Drivers Procurement Notes

Verify the ordering suffix 'DGKR' corresponds to the 8-VSSOP package and tape-and-reel quantity. Confirm that the specified voltage levels match the target PECL circuit requirements. Check for RoHS compliance status as per current manufacturer documentation. Ensure the operating temperature range meets the environmental constraints of the final assembly.

Clock Buffers, Drivers Selection Notes

Select this component when a single-ended or differential source requires splitting into two matched PECL paths. Compare propagation delay and skew specifications against system timing budgets. Verify power consumption limits relative to available thermal dissipation in the VSSOP-8 footprint. Consider pin compatibility if replacing legacy buffers in existing layouts.

Clock Buffers, Drivers Part Context

This part belongs to the SN65LVELxx series of low-voltage ECL/PECL drivers. It shares functional similarities with the SN65EL11 but is optimized for lower voltage operation. The DGK variant denotes the tube packaging, while DGKR specifies the reel format. It complements other interface solutions like the SN65LVDS series for mixed-signal systems.

Clock Buffers, Drivers Replacement Considerations

The SN65LVEL11DGK is the tube-packaged equivalent of this reel-based component. Cross-reference with SN65EL11 for higher voltage PECL/ECL applications. Verify pinout compatibility before substituting with generic 1:2 fanout buffers.
