CXA2060AS

Achieving a Common Chassis Worldwide Y, C, and Synchronizing Signal Processing ICs CXA2060AS CXA2061S Sony provides an extensive lineup of Y, C, and synchronizing signal processing ICs (YCD). These ICs take advantage of earlier TV ICs and in addition adopt new technologies to incorporate even more peripheral components and functionality in the same chip. The CXA2060AS supports NTSC, PAL (including PAL-M and PAL-N), and SECAM, whereas the CXA2061S is a special-purpose NTSC YCD chip. Thus the pin compatible CXA2060AS and CXA2061S support all TV broadcast regions and can achieve a common chassis worldwide. s s s s s s Reduced peripheral components count On-chip 1H delay line On-chip SECAM decoder On-chip video switch Three crystal oscillator pin sets for PAL-M and PAL-N support The CXA2060AS and CXA2061S are pin compatible. Worldwide Horizontal Deployment The CXA2060AS is a single-chip Y,C, and synchronizing signal processing IC (YCD) that includes both a 1H delay line and a SECAM decoder on chip, and the CXA2061S is a special-purpose NTSC YCD. While it goes without saying that these chips are pin compatible, their I2C control registers are also identical, making them software compatible as well. These two products were designed to allow a common chassis to be used in all TV broadcast regions. Figure 1 shows the block diagram of the CXA2060AS. Built-in 1H Delay Line and SECAM Decoder The CXA2060AS includes an on-chip 1H delay line and an on-chip SECAM decoder. While earlier products such as the CXA2000Q required an external 1H delay line for PAL and an external SECAM decoder for SECAM, by including these circuits on chip, the CXA2060AS allows the same circuit to provide the different types of signal processing required by NTSC, PAL, and SECAM. This allows the same chassis to be used for all reception areas, including NTSC-only areas, PAL/SECAM areas, and NTSC/PAL-M/PAL-N areas. this single chip can completely support all aspects of a color system. Vertical Deployment from the Low End to the High End Since these chips also provide Y and color difference signal input/output, a feature block can be added. Since an fsc output is provided, a digital comb filter can be used. Thus these chips support flexible deployment in higher grade television systems. The CXA2060AS and the CXA2061S not only aim for extensive and complete television functionality, but also promise the achievement of a common chassis worldwide. Reduced Peripheral Components Count Figure 2 presents a sample application circuit. In addition to the components used in this system, a video switch, a 1H delay line, and a SECAM decoder would be required to construct the same system using earlier products. The CXA2060AS includes these devices on chip. (The CXA2061S only includes the video switch on chip.) Since a high-performance sync separator system for the input signal is fully included on chip, no separate sync separator circuit input signal is required. Additionally, the sample-and-hold capacitor for the autocutoff circuit (AKB) is built in, and capacitors and an oscillator element are not required for the H/V oscillator. Thus V O I C E We are finally seeing the debut of single-chip support for multiformat systems! We performed extensive field testing in developing this IC, looking for signals that are difficult to receive in all corners of the world. As a result, this IC achieves the best SECAM discrimination performance of the century! Sony’s engineers strongly recommend that you try this IC. VMOUT/VPROT G2IN (R-YOUT) B2IN (B-YOUT) R2IN (YOUT) XTAL3 (FSC OUT) Y CLAMP 45 48 47 46 44 40 8 1 SW NTSC, PAL/ SECAM Killer 15 39 38 37 36 28 27 26 25 EYUV Clamp YUV SW YUVOUT Color Amp.
