The HMP8112 is a high quality, digital video, color decoder with
internal A/D converters. The A/D function includes a 3:1 analog
input mux, Sync Tip AGC, Black clamping and two 8-bit A/D
Converters. The high quality A/D converters minimize pixel jitter
and crosstalk.
The decoder function is compatible with NTSC M, PAL B, D,
G, H, I, M, N and special combination PAL N video stan-
dards. Both composite (CVBS) and S-Video (Y/C) input for-
mats are supported. A 2 line comb ï¬lter plus a user
selectable Chrominance trap ï¬lter provide high quality Y/C
separation. Various adjustments are available to optimize
the image such as Brightness, Contrast, Saturation, Hue and
Sharpness controls. Video synchronization is achieved with
a 4xfSC chroma burst lock PLL for color demodulation and
line lock PLL for correct pixel alignment. A chrominance sub-
sampling 4:2:2 scheme is provided to reduce chrominance
bandwidth.
The HMP8112 is ideally suited as the analog video interface
to VCRâs and cameraâs in any multimedia or video system.
The high quality Y/C separation, user ï¬exibility and inte-
grated phase locked loops are ideal for use with todayâs pow-
erful compression processors. The HMP8112 operates from
a single 5V supply and is TTL/CMOS compatible.
