HMP8154, HMP8156A
NTSC/PAL Encoders
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.
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.
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.
The DACs can drive doubly-terminated (37.5
Ω) 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.

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.
