Supports WST, PDC, VPS, and WSS acquisition, with capacity for up to 10 pages of on-chip teletext (expandable to 1000 pages via external SRAM). Audio Processing:
: Manages the timing and output for CRT or LCD panels. vct49x3f py f1000 datasheet
: It controls the horizontal and vertical deflection signals required for CRT (Cathode Ray Tube) displays. On-Screen Smart Features : Supports WST, PDC, VPS, and WSS acquisition, with
This IC operates as a , a design choice that enhances power efficiency and modulation accuracy by handling signal amplitude and phase components separately. Key technical functions include: On-Screen Smart Features : This IC operates as
The VCT49X3F series is now largely considered an obsolete or "hard-to-find" part due to the shift from CRT to LCD/OLED technology.
Likely yes. Most VCT-series analog tuner ICs were phased out around 2015 with the global switch to digital-only tuners (silicon tuners like Si2151). Stock may only be available from surplus or aftermarket repair suppliers.
