Product details
Overview
TW9910-LB2-GR from Renesas Electronics (formerly Intersil) is a low-power analog video decoder IC supporting NTSC/PAL/SECAM with automatic format detection, integrated 4-H adaptive comb filter, digital sub-carrier PLL, and VBI slicer. It delivers ITU-R BT.656-compliant YCbCr 4:2:2 output at up to 27 MHz pixel clock, consumes <100 mW typical power, and operates from 1.8 V core / 3.3 V I/O supplies.
For engineers reviewing the TW9910-LB2-GR datasheet, TW9910-LB2-GR pinout, TW9910-LB2-GR application, or TW9910-LB2-GR equivalent, key selection considerations include VBI data service support (e.g., closed captioning, teletext), horizontal scaling capability with arbitrary down-ratio, phase accuracy better than 1/32 pixel, and dual-crystal frequency flexibility (27 MHz standard, 24.54/29.5 MHz for square-pixel formats).
Technical Context
The TW9910-LB2-GR implements a fully digital synchronization processor with line-lock clock generation and advanced sync detection for non-standard or weak analog video signals. Its dual 10-bit ADCs feed a luma/chroma processor featuring programmable white peak control, automatic gain control, and chroma IF compensation.
Video path processing includes 4-H adaptive comb filtering for Y/C separation, PAL delay line for color phase correction, and image enhancement via peaking and CTI. The VBI slicer extracts industrial-standard data services directly from the vertical blanking interval without external components.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7180BCPZ | Single 10-bit ADC; no built-in VBI slicer; requires external microcontroller for VBI data extraction | Lacks native closed captioning/teletext parsing; limited to basic CVBS-to-Digital conversion | Select when VBI functionality is handled externally and lower pin count (32-pin LFCSP) is prioritized |

FAQ
What video standards does the TW9910-LB2-GR support?
The TW9910-LB2-GR supports NTSC (M, 4.43), PAL (B, D, G, H, I, M, N, N-combination), PAL(60), and SECAM with automatic format detection. It uses digital PLLs and adaptive processing to maintain accurate color decoding and sync recovery across all supported standards without manual configuration.
Does the TW9910-LB2-GR include a built-in VBI slicer?
Yes, the TW9910-LB2-GR integrates a dedicated VBI slicer supporting industrial-standard data services including closed captioning (EIA-608/EIA-708), teletext, and WSS. It can extract and output VBI data alongside raw ADC samples or processed YCbCr video, eliminating the need for external VBI decoding circuitry.
What are the power supply requirements for the TW9910-LB2-GR?
The TW9910-LB2-GR requires separate 1.8 V for core logic and 3.3 V for I/O and analog circuitry. Its 3.3 V-tolerant I/O pins simplify interface design with common microcontrollers and FPGAs. Typical operating power consumption is less than 100 mW, making it suitable for thermally sensitive embedded video applications.
Can the TW9910-LB2-GR perform horizontal scaling?
Yes, the TW9910-LB2-GR includes an integrated horizontal scaler with arbitrary down-scaling capability and phase accuracy better than 1/32 pixel. This allows precise resizing of decoded video for display or processing pipelines without introducing visible aliasing or timing jitter in the output stream.
What package type is used for the TW9910-LB2-GR?
The TW9910-LB2-GR is supplied in a 44-pin LQFP package (10 mm × 10 mm, 0.8 mm pitch) with exposed thermal pad. This RoHS-compliant package supports reflow soldering and provides adequate thermal dissipation for its <100 mW power profile in compact PCB layouts.
