Renesas TW9910-LA2-GR

Overview

TW9910-LA2-GR from Renesas Electronics (formerly Intersil) is a low-power analog video decoder IC supporting NTSC/PAL/SECAM with automatic format detection, integrated VBI slicer, 4-H adaptive comb filter, and ITU-R BT.656-compatible YCbCr(4:2:2) output. It operates from 1.8V/3.3V supplies, consumes <100mW typical, and targets legacy video capture in embedded surveillance and automotive rear-view systems.

For engineers reviewing the TW9910-LA2-GR datasheet, TW9910-LA2-GR pinout, TW9910-LA2-GR application, or TW9910-LA2-GR equivalent, key selection criteria include analog input flexibility (up to 4 CVBS or 3 CVBS + 1 Y/C), VBI data pass-through capability, horizontal PLL stability for weak-signal sync, and LQFP-44 package compatibility with legacy board layouts.

Technical Context

The TW9910-LA2-GR integrates dual 10-bit ADCs with analog clamping and programmable AGC for the Y channel, plus chroma IF compensation and PAL delay line for color phase correction. Its digital sub-carrier PLL ensures accurate color decoding across all supported standards.

It features advanced synchronization processing for non-standard and weak signals, real-time control interface support, and high-quality horizontal scaling with arbitrary down-ratio and <1/32-pixel phase accuracy. The VBI slicer complies with industrial standard data services including closed captioning and teletext.

FAQ

What video standards does the TW9910-LA2-GR support?

The TW9910-LA2-GR supports NTSC (M, 4.43), PAL (B, D, G, H, I, M, N, N-combination), PAL(60), and SECAM with automatic format detection. This multi-standard capability eliminates manual configuration and enables single-hardware deployment across North America, Europe, Asia, and Russia. The TW9910-LA2-GR uses digital sub-carrier and horizontal PLLs to maintain lock and decode accuracy even with marginal signal quality.

Does the TW9910-LA2-GR include a VBI slicer, and what data services does it handle?

Yes, the TW9910-LA2-GR integrates a VBI slicer compliant with industrial standards including closed captioning (EIA-608), teletext (ETSI EN 300 231), WSS (Wide Screen Signaling), and VPS (Video Programming System). It also supports raw ADC data output for custom VBI protocols. The TW9910-LA2-GR's VBI slicer operates concurrently with video decoding without performance penalty.

What package type and pin count does the TW9910-LA2-GR use?

The TW9910-LA2-GR is supplied in a 44-pin LQFP package (10mm × 10mm, 0.8mm pitch) with exposed thermal pad. This footprint matches legacy video decoder layouts and supports reflow soldering per JEDEC J-STD-020. The TW9910-LA2-GR's pinout includes dedicated analog inputs (CIN0–CIN3), BT.656 video output (VD[15:0], VS, HS), and I²C control (SCLK/SDAT), all verified in the official Renesas datasheet FN7773.

Can the TW9910-LA2-GR perform video scaling, and what are its scaling capabilities?

Yes, the TW9910-LA2-GR includes an integrated horizontal video scaler with arbitrary down-scaling ratio and phase accuracy better than 1/32 pixel. It supports programmable output cropping and maintains timing integrity during scaling. The TW9910-LA2-GR does not provide vertical scaling; its scaler is optimized for horizontal resampling to match pixel clocks of downstream SoCs or FPGAs.

What power supply voltages and consumption does the TW9910-LA2-GR require?

The TW9910-LA2-GR operates from a 1.8V core supply and 3.3V I/O supply, with 3.3V-tolerant digital pins. Typical power consumption is less than 100mW under full operation with all features enabled. The TW9910-LA2-GR supports power-save and power-down modes, reducing current to <1µA in PDN state - essential for battery-powered portable video analyzers.
