NTSC/PAL Video Encoder
Features
The HMP8170, HMP8171, HMP8172, and HMP8173 NTSC
and PAL encoders are designed for use in systems requiring
the generation of high-quality NTSC and PAL video.
• (M) NTSC and (B, D, G, H, I, M, N, NC) PAL Operation
• BT.601 and Square Pixel Operation
• Digital Input Formats
- 8-bit, 16-bit 4:2:2 YCbCr
- 8-bit BT.656
YCbCr digital video data drive the P0-P15 inputs. The Y data
is optionally lowpass filtered to 6MHz and drives the Y analog
output. Cb and Cr are each lowpass filtered to 1.3MHz,
quadrature modulated, and added together. The result drives
the C analog output. The digital Y and C data are also added
together and drive the two composite analog outputs.
• Analog Output Formats
- Y/C + Two Composite
- RGB + Composite
- YUV + Composite
The DACs can drive doubly-terminated (37.5Ω) lines, and
run at a 2x oversampling rate to simplify the analog output
filter requirements.
• Flexible Video Timing Control
- Timing Master or Slave
- Selectable Polarity on Each Control Signal
- Programmable Blank Output Timing
Applications
• DVD Players
• “Sliced” VBI Data Support
- Closed Captioning
• Video CD Players
• Digital VCRs
- Widescreen Signalling (WSS)
- BT.653 System B and C Teletext
• Multimedia PCs
