NTSC/PAL Encoders
Features
• (M) NTSC and (B, D, G, H, I, M, N, CN) PAL Operation
• ITU-R BT.601 and Square Pixel Operation
The HMP8154 and HMP8156A NTSC and PAL encoders are
designed for use in systems requiring the generation of high-
quality NTSC and PAL video from digital image data.
• Digital Input Formats
- 4:2:2 YCbCr
YCbCr or RGB digital video data drive the P0-P23 inputs.
Overlay inputs are processed and the data is 2x upsampled.
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 summed. The result
drives the C analog output. The digital Y and C data are also
added together and drive the two composite analog outputs.
- 8-Bit or 16-Bit
- 4:4:4 RGB
- 16-Bit (5, 6, 5) or 24-Bit (8, 8, 8)
- Linear or Gamma-Corrected
- 8-Bit BT.656
• Overlay Mixing
The YCbCr data may also be converted to RGB data to drive
the DACs, allowing support for analog component RGB and
the European SCART connector.
- 7 Colors
- Internal, External, or Hard Mixing Control
• Analog Output Formats
- Y/C + Two Composite
The DACs can drive doubly-terminated (37.5Ω) lines, and
run at a 2x oversampling rate to simplify the analog output
filter requirements. Any unused DACs may be powered down
to reduce power consumption.
- RGB + Composite (SCART)
• Flexible Video Timing Control
- Timing Master or Slave
Ordering Information
- Programmable Input Sync Timing
- Selectable Polarity on Each Control Signal
- Programmable Blank Output Timing
- Field Output

NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
compatible with both SnPb and Pb-free soldering operations. Intersil
Pb-free products are MSL classified at Pb-free peak reflow
temperatures that meet or exceed the Pb-free requirements of
IPC/JEDEC J STD-020.
