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
