• Wider band for signal processing (Y: 30 MHz/−3 dB,
color difference: 15 MHz/−3 dB)
• Direct input of HD, NTSC and DVD standard YUV signal
• High picture quality due to the built-in various correction circuits of Y signal
• Auto-cut off functions
• Having 2 systems of RGB input, OSD plus character
broadcasting or external RGB input such as VGA is
supported.
• SMD package allows for high density mounting.

High input: V48 ≥ 2.1 V
Low input: V48 ≤ 0.9 V
• The data for color, tint, brightness and
contrast will be re-written at the time when
VP pulse goes high to low. But at DAC SW
(V-latch Mode): In the through mode, the
data will be rewritten according to the timing
sent, regardless of VP pulse.
• Auto cutoff timing pulse will be generated
according to VP pulse.
• Be sure to keep the VP pulse width more
than 6H.
• Recommended use range: 0 V to 5 V
