NCS2553
3-Channel Video Amp with
Standard Definition
Reconstruction Filters
Description
The NCS2553 is a 3−channel high speed video amplifier with 6th
order butterworth standard definition reconstruction filter.
All three channels can accommodate either all component and RGB
video signals or composite and S−Video signals. All channels can
accept DC or AC coupled signals. If AC coupled, the internal clamps
are employed. The outputs can drive both AC and DC coupled 150 W
loads.
It is designed to be compatible with most digital−to−analog
converters (DAC) embedded in most video processors.
Feature
• Three 6th Order Standard Definition 8 MHz Filters
• Internally Fixed Gain = 6 dB
• AC− or DC− Coupled Inputs
• AC− or DC− Coupled Outputs
• Integrated Level Shifter
• Operating Voltage +5 V
• Available in a SOIC−8 Package
• These are Pb−Free Devices
Applications
• Digital Set−Top Box
• DVD / Video Players and Related
• SD−TV
• Video On Demand (VOD)
• Video Recorders
