Renesas TW9919-PE1-GR

Overview

TW9919-PE1-GR from Intersil is a 128-pin PQFP 5×10-bit multi-standard video processor supporting NTSC/PAL/SECAM decoding, SCART RGB mixing, and 3D comb filtering for embedded multimedia systems. It integrates five 10-bit ADCs, adaptive 4H/3D comb filters, VBI slicer/FIFO, and ITU-R 601/656 YCbCr(4:2:2) output with programmable scaling and cropping.

For engineers reviewing the TW9919-PE1-GR datasheet, TW9919-PE1-GR pinout, TW9919-PE1-GR application, or TW9919-PE1-GR equivalent, key selection considerations include analog input flexibility (6 composite / 2 S-Video / 2 YCbCr / 2 SCART RGB), 27MHz crystal dependency, 0.6W typical power consumption, and VBI data pass-through capability for Intercast™.

Technical Context

The TW9919-PE1-GR implements mixed-signal 2.5V/3.3V CMOS architecture with integrated anti-aliasing filters, clamping circuits, and AGC for Y/G(Y) channels. Its motion-adaptive 3D comb filter operates concurrently with 3D noise reduction, while digital sub-carrier PLL ensures accurate color decoding across all supported standards.

Synchronization processing includes line-locked and free-running clock outputs, field-locked audio clock generation, and advanced horizontal PLL for non-standard video signals. VBI handling features built-in slicer, filter, FIFO, and raw ADC data pass-through for industrial data services including Intercast™.

FAQ

What video standards does the TW9919-PE1-GR support?

The TW9919-PE1-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 sub-carrier PLL and PAL delay line for accurate color decoding across all variants. The TW9919-PE1-GR also handles weak-signal and VCR trick-mode synchronization robustly.

Does the TW9919-PE1-GR support RGB overlay functionality?

Yes, the TW9919-PE1-GR supports analog RGB/YCbCr mixing via Fast Blanking (FB0/FB1) inputs, enabling real-time hardware overlay of graphics onto decoded video. It accepts up to two SCART RGB inputs with feedback, and mixing is fully programmable through its two-wire serial interface. This capability is integral to the TW9919-PE1-GR's role in consumer AV hubs.

What is the function of the VBI FIFO in the TW9919-PE1-GR?

The TW9919-PE1-GR includes a built-in VBI FIFO that buffers sliced and filtered VBI data (e.g., closed captioning, teletext) for deterministic host access. It supports data packet filtering and raw ADC pass-through for Intercast™. This FIFO decouples VBI data capture from video frame timing, ensuring reliable metadata extraction in the TW9919-PE1-GR.

What power supplies are required for the TW9919-PE1-GR?

The TW9919-PE1-GR requires separate 2.5V for analog core (VDDA_2P5) and 3.3V for analog I/O (VDDA_3P3), plus 3.3V digital supply. Its I/O pins are 3.3V/5V tolerant. Total typical power consumption is 0.6W. The TW9919-PE1-GR achieves this efficiency using mixed-signal CMOS process and integrated front-end functions.

Is the TW9919-PE1-GR pin-compatible with other Techwell/Intersil video decoders?

No, the TW9919-PE1-GR is not pin-compatible with other Techwell/Intersil video decoders such as the TW9900 or TW9912 due to differences in pin assignment, package size (128-pin PQFP), and functional allocation (e.g., FB0/FB1, VBI FIFO control). The TW9919-PE1-GR has a unique pinout optimized for its SCART mixing and VBI architecture.
