Description
Toshiba has designed two application-
specific modules based on the
TC90407XBG digital TV SoC that can
reduce design-to-production time:
– DLVM-GC
– DLVM-GL
The DLVM-GC module is designed for
digital CRT TV applications and the DLVM-
GL module is designed for LCD TV
applications. Both modules decode digital
transmission content and provide analog or
digital output to existing backend
processors in TV systems that decode
analog transmissions for display. The
DLVM-GC module can be plugged into an
existing analog CRT chassis or mother-
board through a connector. Similarly, the
DLVM-GL module can be plugged into an
TC90407XBG Reference Modules
1
existing LCD TV backend processor system
that decodes analog transmission for display.
Features
Hardware Structure: The block diagram of
the DLVM-GC module is based on the
Toshiba TC90407XBG digital TV SoC. The
digital tuner IF output is connected to the
VSB demodulator input of the TC90407XBG
chip on the module. The DLVM-GC can
decode HD or SD stream and provide analog
output in 480i format (CVBS, S-Video or
Component Video) for digital CRT TV
applications. It can also provide component
analog output in 480p/720p/1080i format.
This module generates analog stereo audio
output and digital audio output (SPDIF). The
DLVM-GC module design can also be used
for digital converter box applications.
