Product details
Overview
PI7VD9008ABH from Diodes Incorporated (acquired Pericom) is an 8-channel adaptive equalizing video decoder and audio codec for analog CCTV systems. It supports NTSC/PAL/960H CVBS inputs, integrates 10-bit ADCs per channel, a proprietary AEQ for coax cable signal recovery up to several hundred meters, and outputs ITU-R BT.656-compliant YCbCr streams at 54/108 MHz or 72/144 MHz for DVR and automotive ADAS video capture.
For engineers reviewing the PI7VD9008ABH datasheet, PI7VD9008ABH pinout, PI7VD9008ABH application, or PI7VD9008ABH equivalent, key selection considerations include real-time 8-channel WD1/960H decoding capability, built-in 10-bit audio codec with I²S/DSO support, industrial temperature range (−40°C to +85°C), and programmable video processing features including 5H comb filtering and CTI.
Technical Context
The PI7VD9008ABH implements eight independent analog video front-ends, each with a 10-bit ADC, proprietary clamp circuit, automatic gain control, and 5H comb filter optimized for NTSC and PAL standards. Its adaptive equalizer dynamically compensates for high-frequency loss in long coax runs without external tuning.
Video processing is synchronized to a single 27 MHz crystal, enabling simultaneous NTSC, PAL, and 960H operation. The integrated video PLL generates precise 108 MHz or 144 MHz pixel clocks, while dual serial audio interfaces (I²S and DSP modes) support flexible recording/mixing with sample rates from 8 kHz to 48 kHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar 8-channel analog video decoding applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TI TVP5160AM1 | Single-channel decoder; requires 8x ICs for full 8-channel support; no integrated audio codec | Limited to lower channel count systems; lacks AEQ and coax compensation | Choose when only one or two channels needed and cost-per-channel outweighs board space constraints |
| Maxim MAX9526 | Single-channel 10-bit decoder with embedded AEQ; no multi-channel integration or audio codec | Designed for compact single-camera modules; no BT.656 multiplexing or GPIO expansion | Prefer for space-constrained edge devices where channel density is secondary to footprint |
Compared with TVP5160AM1 and MAX9526, the PI7VD9008ABH uniquely delivers true 8-channel parallel decoding, integrated audio handling, and coax-aware AEQ in a single LQFP package-reducing BOM count, PCB area, and system-level signal integrity challenges in multi-camera analog HD systems.

FAQ
What video standards does the PI7VD9008ABH support?
The PI7VD9008ABH supports NTSC (M, 4.43), PAL (B, D, G, H, I, M, Nc, 60), and 960H (WD1) composite video standards. All standards are handled concurrently using a single 27 MHz crystal reference, with automatic format detection and adaptive equalization applied per channel.
Does the PI7VD9008ABH require external memory or firmware?
No. The PI7VD9008ABH operates autonomously with no external memory or firmware required. Configuration is performed via I²C register writes, and all video processing-including 5H comb filtering, AEQ adaptation, and BT.656 formatting-is implemented in hardwired logic.
Can the audio and video paths operate independently?
Yes. The audio codec (10-in/1-out) and video decoder (8-in) are functionally independent. Audio sampling (8–48 kHz) and video decoding (NTSC/PAL/960H) use separate clock domains, and their I²S/DSO and BT.656 interfaces can be enabled or disabled individually via register control.
Is the PI7VD9008ABH still in active production?
Although marked "OBSOLETE – PART DISCONTINUED" in some legacy documentation, Diodes Incorporated continues to support the PI7VD9008ABH through authorized distribution channels with confirmed inventory and controlled lifetime buy programs for existing designs.
