GF9105ACQQ

Encoders, Decoders, Converters Overview

The GF9105ACQQ is a MultiGENTM Component Digital Transcoder manufactured by Gennum. It serves as a drop-in replacement for the GF9105, offering lower power consumption and expanded functionality. The device supports multiple format conversions including 4:2:2:4 to 4:4:4:4, R/G/B/KEY, and Y/U/V/KEY. It features ITU-R-601 compliant interpolation and decimation filters, supporting both single link (SMPTE RP174) and dual link (SMPTE RP175) I/O. The unit includes a fully programmable 3x3 Color Space Converter with 13-bit coefficients and a 13-bit KEY Channel scaling coefficient. It operates on a single +5V power supply.

Encoders, Decoders, Converters Feature Summary

• Performs flexible VDSP engine operations for various format conversions and general DSP functions requiring a 3x3 multiplier structure.
• Provides transparent conversions between Y/U/V and R/G/B color spaces with bi-directional I/O data ports capable of tri-stating.
• Includes optimized HOST IF control signals to ensure shared bus compatibility and supports low frequency clocks with non-multiplexed I/O data.
