TMC2491A - Multistandard Digital Video Encoder

Download the TMC2491A datasheet PDF. This datasheet also covers the TMC2490A variant, as both devices belong to the same multistandard digital video encoder family and are provided as variant models within a single manufacturer datasheet.

General Description

The TMC2490(1)A video encoder converts digital component video (in 8-bit parallel CCIR-601/656 or ANSI/SMPTE 125M format) into a standard analog baseband television (NTSC, NTSC-EIA, and all PAL standards) signal with a modulated color subcarrier.

Key Features

  • All-digital video encoding.
  • Internal digital subcarrier synthesizer.
  • 8-bit parallel CCIR-601/CCIR-656/ANSI/SMPTE 125M input format.
  • CCIR-624/SMPTE-170M compliant output.
  • Switchable chrominance bandwidth.
  • Switchable pedestal with gain compensation.
  • Pre-programmed horizontal and vertical timing.
  • 13.5 Mpps pixel rate.
  • Master or slave (CCIR656) operation.
  • MPEG interface.
  • Internal interpolation filters.
