CXA2060BS
Y/C/RGB/D for PAL/NTSC/SECAM Color TVs For the availability of this product, please contact the sales office.
Description The CXA2060BS is a bipolar IC which integrates the luminance signal processing, chroma signal processing, RGB signal processing, and sync and deflection signal processing functions for PAL/ NTSC/SECAM system color TVs onto a single chip. This IC includes deflection processing functions for wide-screen TVs. With a SECAM decoder and 1H delay line built in for PAL/SECAM, this IC can be used in configuring multi-color system TV set. 48 pin SDIP (Plastic)
Features * Supports the I2C bus * 1H delay line and SECAM decoder * Supports NTSC/PAL-N/PAL-M systems with three crystal pins * Deflection compensation circuit for support of various wide modes * Count down system eliminates need for V oscillation frequency adjustment * Automatic identification of 50/60Hz vertical frequency (forced control possible) * Supports non-interlace display (even/odd selectable) * Automatic identification of PAL, NTSC and SECAM color systems (forced control possible) * Automatic identification of 4.43MHz/3.58MHz for crystal (forced control possible) * No adjustment of Y/C filter required * Three CV inputs, two Y/C inputs (Y/C input shared with CV input), one Y/C input supporting external comb filter, two RGB inputs * Dynamic picture/dynamic color circuit * AKB and gamma correction circuits * YS1 can be forcibly turned OFF * FSC output (shared with PAL-N crystal pin) Applications Color TVs (4:3, 16:9) Structure Bipolar silicon monolithic IC Absolute Maximum Ratings (Ta = 25C, GND1, 2 = 0V) V * Supply voltage VCC1, 2 -0.3 to +12 * Operating temperature Topr -20 to +75 C * Storage temperature Tstg -65 to +150 C * Allowable power dissipation PD 1.5 W (When mounted on a 50mm x 50mm board) * Voltage at each pin -0.3 to VCC1, 2 + 0.3 V Operating Conditions Supply voltage
