DATA SHORT To request the full datasheet, please visit www.intersil.com/products/TW9906 TW9906 FN7770 Rev.0.00 3x10-bit Multi-Standard Comb Filter Video Decoder with YCbCr Component Input February 11, 2011 Intersil Techwells TW9906 is a high quality Programmable hue, brightness, saturation, contrast, and NTSC/PAL,/SECAM multi-standard video decoder plus YCbCr sharpness component inputs designed for multimedia applications. Blue stretch TW9906 uses the mixed-signal 2.5V/3.3V CMOS technology to Image enhancement with 2D peaking and CTI. provide a low-cost and low-power integrated solution. Automatic color control and color killer Minimum external components are required due to its IF compensation filter integrated analog front-end containing anti-aliasing filter, AGC, clamping, and three 10-bit high speed ADCs. For composite Detection of level of copy protection according to inputs, an adaptive comb filter and luma/chroma processing Macrovision standard produce exceptionally high quality pictures using proprietary YCbCr input supports 480i/576i and sub-sampled techniques. A high quality internal scaling engine offers 480p/576p with auto-detection. arbitrarily filtered down scaling of the output video. Its VBI capability is enhanced with built-in VBI slicer, filter, FIFO and Video Output VBI data pass-through function to support common data Support both free-running and line-locked clock outputs services. Programmable output cropping Features High quality horizontal filtered scaling with arbitrary scale NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N combination), down ratio PAL (60), SECAM support with automatic format detection VMI 1.4 compatible 10-bit or 20-bit pixel interface Advanced synchronization processing for VCR trick mode ITU-R 601 or ITU-R 656 compatible output YCbCr(4:2:2) and weak signal output format Software selectable analog inputs allows any of the VBI slicer supporting industrial standard data services with following combinations: data packet filter capability - Up to five composite video inputs Built-in VBI FIFO for convenient access through host - Four composite, one S-video or one YCbCr input. interface - Two composite, two S-Video or two YCbCr inputs. VBI data pass through, raw ADC data for Intercast - Three composite, one S-Video and one YCbCr input. Field locked audio clock generator Three 10-bit ADCs with clamping circuit and anti-aliasing filter. Miscellaneous Fully programmable static or automatic gain control for the Two wire MPU serial bus interface Y channel Power-down mode Programmable white peak control for the Y channel Typical power consumption 0.25W Adaptive 4H comb filter for the best image quality.
