Description
The TMC2360 converts RGB video and sync from a stan-
dard VGA source into NTSC or PAL video. Composite and
S-Video outputs are compliant with SMPTE-170M and
CCIR-656 specifications. A fully-integrated 3-line flicker
filter provides three selectable operating modes.
Reference designs are available from the factory. System
implementation requires an absolute minimum of external
components. Critical timing is derived from a single 27 MHz
crystal or an external clock reference.
All functions are directly controlled via package pins. Video
and filtering modes may be programmed through either a
microcontroller port or Vertical Sync Communications
(VSCOM). VESA Display Power Management Signaling
(DPMS) is supported.
Power is derived from a single +5V supply. Package is an
80-lead Metric Quad Flat Pack (MQFP), 2.7mm (KL)
package thickness.
