Analog Video Front-End Processors
Related Information

The Toshiba family of analog/video front-end processors simplify analog interface design and enhance the end-user experience through integration of video switching, synchronization, real-time detection of television and computer video formats, cut-off frequency pre-filters for ADCs, and I2C bus control. The devices are targeted at television, set-top box, audio/video receiver and video converter/switch applications for processing of high bandwidth component video.

Product Family

The TB1311AFG and TB1328FG include a programmable analog/video switch block that can be configured to provide the quantity and type of video inputs needed for a variety of end-product designs. The devices also integrate a real-time format detector and automatic sync processor that reduce board real estate, engineering time and product cost compared to separate video and audio switches and low-pass filters. TB1311AFG is typically used in applications where two video inputs are required, like a picture-in-picture display and TB1328FG is used in applications where single-video input is required.

TB1311AFG Analog/Video Switch
  • Configurable for a variety of applications
  • Integrates a real-time format detector and automatic sync processor

TB1328FG Analog/Video Switch
  • Programmable audio/video switch with frequency detection
  • Single output reduces cost for applications where only one output is required.
