LA7138M
Overview
The LA7138M is a video output interface IC for DVD players. It is an ideal DVD player driver IC that generates analog
video signals such as composite/S and component/RGB signals. Incorporating Y/C-MIX, the LA7138M can dispense with
the composite output that would otherwise have to be provided by a DA converter.
Feature
• Video S/N ratio: -80dB.
• f characteristics: 10MHz flat.
• Y/C time difference: 2ns maximum.
• Signal dynamic range: 170 IRE.
• Supports all types of video signals including the composite/S, component, and base-band (RGB) signals; the internal input
configuration is selected under microcontroller control (input capacitors to be used in common).
• Provides two channels of 75Ω driver outputs each of which can be muted on and off independently under microcontroller
control.
• Internally generates clamp pulses that are necessary when receiving the component input signals.
• The amplifier gain is selectable from 8.5dB and 6dB.
• The on-chip regulator circuit provides stable DC voltages that are immune to VCC fluctuations.
Function
• Clamp.
• Amplifier.
• 75Ω driver.
• Y/C-MIX.
• DC voltage output for S1 and S2.
