Product details
Overview
TW2960-LA1-CR from Intersil is a 4-channel 960H video decoder and audio codec IC supporting NTSC/PAL auto-detection, four 10-bit CVBS ADCs, 4-H adaptive comb filtering, ITU-R BT.656 YCbCr(4:2:2) output at 72/144MHz, and integrated five-channel audio ADC + single DAC with I²S/PCM interface - deployed in multi-channel DVR systems for analog CCTV camera aggregation.
For engineers reviewing the TW2960-LA1-CR datasheet, TW2960-LA1-CR pinout, TW2960-LA1-CR application, or TW2960-LA1-CR equivalent, key selection considerations include analog input channel mapping (VIN1A/B–VIN4A/B), BT.656 timing compliance, audio sample rate programmability (8–48kHz), and 100-pin LQFP thermal/power layout constraints.
Technical Context
The TW2960-LA1-CR integrates four independent video decoding pipelines, each with analog clamping, 10-bit ADC, 4-H adaptive comb filter, PAL delay line, and digital sub-carrier PLL for precise color demodulation. It supports simultaneous NTSC and PAL format handling via automatic detection and per-channel gain/hue/saturation control.
Audio processing includes five stereo-capable ADCs with decimation filters, one DAC with interpolation filter, and configurable I²S/DSP master/slave interface supporting 8/16-bit PCM and μ-Law/A-Law encoding at 8/16/32/44.1/48kHz sample rates - all synchronized to a single 36MHz crystal-derived 144MHz clock.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 4-channel analog video decoder applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TW2865-NA1-GR | 3-channel decoder; no integrated audio codec; uses external clock generator | Lacks audio path - requires separate audio IC for multi-track recording | Select when only video acquisition is needed and audio is handled externally |
| ADV7180BSTZ | Single-channel SD decoder; 8-bit output; no comb filter; supports only NTSC/PAL-B/G/D | Not scalable to 4-channel systems without multiplexing or multiple ICs | Choose for cost-sensitive single-camera designs where advanced filtering is not required |
Compared with TW2960-LA1-CR, TW2865-NA1-GR reduces integration but increases system-level component count, while ADV7180BSTZ offers lower channel density and simplified feature set - making TW2960-LA1-CR optimal for compact, full-featured 4-channel DVRs requiring co-located audio/video processing.

FAQ
What video standards does the TW2960-LA1-CR support?
The TW2960-LA1-CR supports NTSC (M, 4.43) and PAL (B, D, G, H, I, M, N, N-combination, 60) with automatic format detection. It implements digital sub-carrier PLL and PAL delay line for accurate color decoding across all supported standards. The device does not support SECAM or HD-SDI formats.
Does the TW2960-LA1-CR require external memory or configuration EEPROM?
No, the TW2960-LA1-CR contains internal register space and operates without external memory. Configuration is performed via its two-wire MPU interface (SCLK/SDAT), and default settings are loaded at power-on. No external EEPROM or boot ROM is needed for basic operation of the TW2960-LA1-CR.
Can the TW2960-LA1-CR output RGB or HDMI directly?
No, the TW2960-LA1-CR outputs ITU-R BT.656 YCbCr(4:2:2) or time-multiplexed digital video only. It does not include RGB conversion logic or HDMI transmitter circuitry. External FPGA or SoC must handle YCbCr-to-RGB conversion and HDMI serialization for display output.
What is the maximum input voltage range for CVBS signals on the TW2960-LA1-CR?
The TW2960-LA1-CR accepts standard CVBS signals with 1Vpp amplitude (0.7V video + 0.3V sync). Its analog input structure includes clamping and programmable white peak control to accommodate signal variations up to ±10% without saturation. Exceeding 1.1Vpp risks clipping in the TW2960-LA1-CR ADC front-end.
Is the TW2960-LA1-CR pin-compatible with other Techwell decoder families?
No, the TW2960-LA1-CR is not pin-compatible with earlier Techwell decoders such as TW28xx series. Its 100-pin LQFP layout, BT.656 data bus assignment (VD1–VD4), and integrated audio interface differ significantly. Migration requires PCB redesign and firmware adaptation for the TW2960-LA1-CR.
