Product details
Overview
TW9910-NA2-GR from Renesas Electronics (formerly Intersil) is a low-power analog video decoder IC supporting NTSC, PAL, and SECAM standards with automatic format detection, integrated VBI slicer, 4-H adaptive comb filter, and ITU-R BT.656 YCbCr(4:2:2) output - used in legacy video capture systems for security DVRs and automotive rear-view cameras.
For engineers reviewing the TW9910-NA2-GR datasheet, TW9910-NA2-GR pinout, TW9910-NA2-GR application, or TW9910-NA2-GR equivalent, key selection considerations include VBI data pass-through capability, 10-bit dual ADC performance, 27MHz crystal-based clock architecture, power-down mode operation, and LQFP-44 package compatibility with industrial video front-end designs.
Technical Context
The TW9910-NA2-GR implements a fully digital horizontal PLL for pixel-synchronous sampling and a digital sub-carrier PLL for precise color decoding across all supported standards. Its sync processor handles non-standard and weak analog signals without external timing references.
It integrates two independent 10-bit ADCs with analog clamping and programmable gain control on the Y channel, plus chroma IF compensation and PAL delay line correction - enabling robust luma/chroma separation in noisy broadcast environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Video Standards | NTSC (M, 4.43), PAL (B/D/G/H/I/M/N/N-combination), PAL(60), SECAM - auto-detected without host intervention |
| ADC Resolution | Two independent 10-bit ADCs - enables 60dB dynamic range for CVBS input digitization |
| Output Format | ITU-R BT.656 8-bit YCbCr(4:2:2) parallel output - directly interfaces to ARM/SoC video input ports |
| Power Supply | 1.8V core / 3.3V I/O - supports mixed-voltage system integration with level-tolerant digital interface |
| Power Consumption | <100mW typical - suitable for thermally constrained embedded enclosures and fanless DVR designs |
| Crystal Frequency | 27MHz single crystal - eliminates need for multiple oscillators across NTSC/PAL/SECAM modes |
| VBI Support | Integrated VBI slicer with raw ADC pass-through - extracts closed captioning, teletext, and WSS data from line 21/18/20 |
Pinout & Package
Package: 44-pin LQFP (10mm × 10mm, 0.8mm pitch), RoHS-compliant, moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VD[15:0] | YCbCr(4:2:2) parallel data bus | Upper 8 bits (VD[15:8]) and lower 8 bits (VD[7:0]) deliver time-multiplexed Y/Cb/Cr samples per BT.656 |
| HS, VS, FIELD | Synchronization signals | Horizontal sync, vertical sync, and field ID outputs - enable frame-accurate capture in interlaced video systems |
| SCLK, SDAT | 2-wire serial interface | I²C-compatible control bus - configures decoder registers, gain, hue, saturation, and scaling parameters |
| PDN, RSTB | Power management controls | Active-low power-down and reset pins - allow full standby mode with <1µA leakage current |
| CIN0–CIN3 | Analog video inputs | Four configurable CVBS/Y-C inputs - selectable via internal MUX for multi-channel camera support |
Key Features
| Feature | Design Value |
|---|---|
| 4-H adaptive comb filter | Reduces cross-luminance and cross-color artifacts in composite video without external components |
| Digital sub-carrier PLL | Maintains stable color burst lock across ±10% frequency drift - critical for degraded broadcast signals |
| VBI slicer with pass-through | Extracts line-21 closed captioning and line-18 teletext while forwarding raw ADC data for custom parsing |
| Programmable image enhancement | Independent peaking and chroma transient improvement (CTI) control - adjustable per application lighting conditions |
| Arbitrary horizontal scaling | Down-scaling with phase accuracy better than 1/32 pixel - preserves edge integrity during resolution reduction |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AK8813VN | Single 10-bit ADC, no VBI slicer, supports only NTSC/PAL-B/G | Limited to two-input CVBS; lacks SECAM and raw ADC pass-through | Lower-cost option where VBI and multi-standard support are not required |
| ADV7180BCPZ | 10-bit dual ADC, no built-in scaler, requires external crystal oscillator for each standard | No integrated horizontal scaling; higher BOM count due to discrete PLL components | Better for designs needing ultra-low jitter but accepting added layout complexity |
Compared with AK8813VN and ADV7180BCPZ, the TW9910-NA2-GR uniquely combines SECAM support, integrated VBI slicing, and single-crystal flexibility - reducing component count by up to 7 parts in multi-standard DVR platforms while maintaining medical-grade repeatability.

FAQ
What video standards does the TW9910-NA2-GR support with automatic detection?
The TW9910-NA2-GR supports NTSC (M, 4.43), PAL (B, D, G, H, I, M, N, N-combination), PAL(60), and SECAM - all with fully automatic format detection requiring no host software intervention. This behavior is confirmed in the FN7773 Rev. 1.00 datasheet functional description and block diagram, where the sync processor autonomously identifies standard-specific timing and color burst characteristics.
Does the TW9910-NA2-GR include a built-in VBI slicer, and what data services does it handle?
Yes, the TW9910-NA2-GR integrates a dedicated VBI slicer supporting closed captioning (line 21), teletext (line 18), WSS (line 20), and other industrial-standard data services. It also provides raw ADC data pass-through mode, allowing custom firmware to parse proprietary VBI payloads - a capability explicitly documented in the "VBI Slicer" section of the FN7773 datasheet.
What is the power consumption profile of the TW9910-NA2-GR in active and power-down modes?
The TW9910-NA2-GR consumes less than 100mW in typical active operation and enters sub-1µA standby current in power-down mode when PDN is asserted. These values are measured at 1.8V core and 3.3V I/O, as specified in the "Electrical Characteristics" table of FN7773 Rev. 1.00 - making TW9910-NA2-GR suitable for fanless and thermally isolated enclosures.
Can the TW9910-NA2-GR decode multiple analog inputs simultaneously, and how is input selection managed?
Yes, the TW9910-NA2-GR supports up to four analog inputs (CIN0–CIN3) with software-selectable routing - enabling configurations such as 4× CVBS or 3× CVBS + 1× Y/C. Input selection is controlled via its 2-wire serial interface (SCLK/SDAT), and the internal analog MUX is detailed in Figure 1 of the FN7773 datasheet block diagram.
What output format and interface does the TW9910-NA2-GR provide for connection to host processors?
The TW9910-NA2-GR delivers ITU-R BT.656-compliant 8-bit YCbCr(4:2:2) video data via a 16-bit parallel bus (VD[15:0]), with HS, VS, and FIELD synchronization signals. This interface requires no external FIFO or glue logic and is directly compatible with video input peripherals on Renesas RZ/A, NXP i.MX, and TI AMx SoCs - as verified in the "Video Interface" section of FN7773.
