Renesas TW9960-TA1-GR

Overview

TW9960-TA1-GR from Intersil is a low-power analog video decoder IC supporting NTSC/PAL with automatic format detection, 960H resolution output, ITU-R BT.656 YCbCr (4:2:2) digital video interface, and integrated 10-bit ADCs with 4-H adaptive comb filter. It operates from 1.8V/3.3V supplies, uses a single 36MHz crystal, and targets CCTV DVR front-end systems requiring high-fidelity composite video digitization.

For engineers reviewing the TW9960-TA1-GR datasheet, TW9960-TA1-GR pinout, TW9960-TA1-GR application, or TW9960-TA1-GR equivalent, key selection considerations include analog input flexibility (2× CVBS or 1× Y/C), programmable gain/white peak control, PAL delay line correction, sub-carrier PLL accuracy, and power-down mode support for embedded surveillance platforms.

Technical Context

The TW9960-TA1-GR integrates dual 10-bit ADCs with analog clamping and software-selectable input muxing, enabling simultaneous or independent processing of two CVBS or one Y/C signal. Its digital horizontal PLL ensures precise pixel sampling timing, while the digital sub-carrier PLL delivers stable color decoding across NTSC-M, NTSC-4.43, and multiple PAL variants (B/D/G/H/I/M/N/N-combination).

Advanced sync processing handles non-standard and weak analog signals without external circuitry. The 4-H adaptive comb filter separates luma/chroma with reduced cross-color artifacts, and the PAL delay line corrects color phase errors inherent in PAL-B/G/H broadcast signals.

FAQ

What video standards does the TW9960-TA1-GR support?

The TW9960-TA1-GR supports NTSC-M, NTSC-4.43, and PAL-B/D/G/H/I/M/N/N-combination with automatic format detection. It does not support SECAM or PAL-60. All standards operate from a single 36MHz crystal, eliminating the need for crystal switching or external PLL reconfiguration. The TW9960-TA1-GR's digital sub-carrier PLL maintains stable color decoding across all supported formats without manual intervention.

Does the TW9960-TA1-GR support 960H resolution output?

Yes, the TW9960-TA1-GR is explicitly designed for 960H analog video digitization, delivering 960×480 (PAL) or 960×488 (NTSC) effective resolution via its ITU-R BT.656 YCbCr (4:2:2) output. This exceeds standard D1 resolution and is optimized for high-density CCTV sensor outputs. The TW9960-TA1-GR achieves this using its dual 10-bit ADCs, adaptive comb filter, and line-lock clock generator-no external interpolation or scaling is required.

Can the TW9960-TA1-GR accept both CVBS and Y/C inputs simultaneously?

No-the TW9960-TA1-GR supports either two CVBS inputs or one Y/C (S-Video) pair, selected via software configuration of its internal analog mux. It cannot process CVBS and Y/C concurrently. Input selection is controlled through I²C register writes to the MUX0/MUX1 bits. The TW9960-TA1-GR's dual ADC architecture allows time-multiplexed or parallel acquisition depending on the chosen mode, but only one signal path is active per frame.

What power supply voltages does the TW9960-TA1-GR require?

The TW9960-TA1-GR requires two independent supplies: 1.8V for the core logic and ADC analog section (VDD18), and 3.3V for I/O and digital interface (VDD33). Its I/O pins are 3.3V-tolerant, allowing direct connection to 3.3V microcontrollers without level shifters. The TW9960-TA1-GR draws less than 150mW in active operation and enters sub-10µA power-down mode when PDN is asserted.

Is the TW9960-TA1-GR pin-compatible with other Intersil video decoders?

No, the TW9960-TA1-GR is not pin-compatible with earlier Intersil decoders such as the TW9910 or TW9920. Its 32-pin TQFP footprint, power pin allocation (separate VDD18/VDD33), and dedicated MPOUT/CLKX2 pins reflect a distinct layout optimized for 960H and dual-input operation. Board redesign is required when migrating to or from the TW9960-TA1-GR. The TW9960-TA1-GR datasheet must be consulted for exact routing and decoupling requirements.
