GS4911BCNE3

Overview

The GS4911BCNE3 is a digitally controlled clock synthesis circuit and timing generator manufactured by Semtech. It features genlock capability, allowing multiple devices to synchronize to an input reference signal. The device generates video and audio clocks and timing signals, recognizing input references conforming to 36 different video standards and 16 graphic formats. It supports cross-locking for output synchronization. The component includes pre-programmed settings for eight video and thirteen graphics clocks, with accuracy limited only by the crystal reference.

Feature Summary

• Generates any video or graphics clock up to 165MHz
• Includes one differential and two single-ended video/graphics clock outputs
• Supports audio clock generation and AFS pulse generation
• Recognizes 36 video standards and 16 graphic formats

Applications

• Video clock synthesis systems
• Graphics clock generation
• SMPTE-compliant HD-SDI output connections
• Multi-device genlocking applications

Part Context

The GS4911BCNE3 belongs to the GS4911B/GS4910B family of clock generators. It shares core features with the GS4910B but distinguishes itself by offering audio clocks and AFS pulse generation capabilities, which are absent in the GS4910B variant.
