Product details
Overview
PI7VD9008ABHFDE from Diodes Incorporated (acquired Pericom) is an 8-channel adaptive equalizing video decoder and audio codec IC for analog CCTV systems. It supports NTSC/PAL/960H CVBS inputs, integrates eight 10-bit ADCs with 5H comb filters, built-in AEQ for coax cable signal recovery up to several hundred meters, and outputs ITU-R BT.656 time-multiplexed YCbCr at 54/108 MHz or 72/144 MHz - used in high-resolution analog DVRs and automotive ADAS camera front-ends.
For engineers reviewing the PI7VD9008ABHFDE datasheet, PI7VD9008ABHFDE pinout, PI7VD9008ABHFDE application, or PI7VD9008ABHFDE equivalent, key selection considerations include coax cable length compensation capability, 960H real-time decoding throughput, dual I²S/DSP audio interface configurability, industrial temperature operation (–40°C to +85°C), and BT.656 output timing compliance across 1–4 channel multiplexing modes.
Technical Context
The PI7VD9008ABHFDE implements a parallel 8-channel analog front-end with per-channel clamp, AGC, and adaptive equalization before digitization. Its proprietary AEQ dynamically adjusts equalization coefficients in real time based on input signal integrity, enabling stable decoding over degraded coax channels without manual tuning.
Video processing includes full-standard NTSC/PAL support with 5H comb filtering for luminance/chrominance separation, and a programmable video PLL generating precise 108 MHz or 144 MHz pixel clocks synchronized to a single 27 MHz crystal. Audio path integrates 10-channel analog input mixing, 10-bit A/D and D/A conversion, and selectable master/slave I²S or DSP serial interface 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 | 4-channel only; no integrated AEQ; requires external equalization for long coax; 8-bit ADC | Limited to quad-DVR or lower-resolution systems; lacks 960H optimization and audio codec | Choose when cost sensitivity outweighs channel count and coax reach requirements |
| ON Semiconductor LMH0387 | SDI serializer with no decoding capability; requires upstream decoder; no audio integration | Designed for digital video transport, not analog CVBS acquisition; no AEQ or BT.656 output | Choose only in hybrid analog/digital architectures where decoding occurs elsewhere |
Compared with TVP5160AM1 and LMH0387, the PI7VD9008ABHFDE uniquely delivers 8-channel real-time AEQ, integrated audio codec, and native 960H BT.656 output - making it the sole option for compact, high-channel-count analog DVRs needing coax reach extension without external signal conditioning.

FAQ
Does the PI7VD9008ABHFDE support both NTSC and PAL standards simultaneously?
Yes. The device auto-detects and decodes NTSC (M, 4.43), PAL (B, D, G, H, I, M, Nc, 60) standards per input channel without reconfiguration. Each of the eight video paths operates independently, allowing mixed-standard inputs - e.g., four NTSC and four PAL cameras on one board - with full 5H comb filtering applied per standard.
What is the maximum coax cable length supported with reliable AEQ performance?
Based on Pericom characterization data using 22 AWG RG59 coax, the PI7VD9008ABHFDE maintains stable sync lock and <1% bit error rate in YCbCr output up to 350 meters at 960H resolution. Performance depends on cable quality and ambient noise; evaluation boards include adjustable AEQ training thresholds to optimize for specific installation conditions.
Can the audio interface handle 10 independent microphone inputs?
No. LINE_IN0–LINE_IN9 accept line-level analog signals (–1 V to +1 V), not microphone-level. For mic inputs, external preamplification is required to meet the device's 1 Vpp input range. The internal audio mixer combines all ten channels into one analog output or serial stream, but gain staging must be managed externally for low-level sources.
Is the 128-pin LQFP package lead-free and RoHS compliant?
Yes. The PI7VD9008ABHFDE uses a matte-tin lead finish on its 128-pin LQFP package and complies with EU RoHS Directive 2011/65/EU and JEDEC J-STD-020 moisture sensitivity level 3 (MSL3). Thermal pad soldering is required for thermal performance; recommended reflow profile follows IPC-J-STD-020D.
