CXA2025AS

Y/C/RGB/Sync/Deflection for Color TV

Description

The CXA2025AS is a bipolar IC which integrates

the luminance signal processing, chroma signal

processing, RGB signal processing, and sync and

deflection signal processing functions for NTSC

system color TVs onto a single chip.

48 pin SDIP (Plastic)

The following functions have been added to the

same function IC, CXA2025S.

1) Vertical sync pull-in speed switching function

2) YUV SW Y signal switching function

Features

Absolute Maximum Ratings

(Ta = 25°C, SGND, JGND = 0V)

• I²C bus compatible

• Sync signal processing uses a countdown system

with non-adjusting H/V oscillator frequencies

• Built-in deflection compensation circuit capable of

supporting various wide modes

• Non-adjusting Y/C block filter

• Built-in AKB

• Video signal I/Os: Y/C separation input, Y/color

difference input, analog RGB input and RGB

output

• Supply voltage

• Operating temperature

Topr

• Storage temperature

Tstg

SV^CC, JVCC –0.3 to +12

–20 to +75 °C

–65 to +150 °C

• Allowable power dissipation

P^D

1.5

• Voltages at each pin –0.3 to SVCC, JVCC + 0.3 V

• YUV SW Y signal switching function allows picture

quality adjustment for the Y signal in the same

manner as for the normal Y signal even when

Y/color difference input is selected
