Product details
Overview
PI7VD9008ABH from Diodes Incorporated (acquired Pericom) is an 8-channel adaptive equalizing video decoder and audio codec IC for analog CCTV systems. It decodes NTSC/PAL/960H CVBS inputs into ITU-R BT.656-compliant YCbCr digital video streams, integrates a 10-bit ADC per channel, 5H comb filter, and built-in AEQ for coax cable signal recovery up to several hundred meters - deployed in high-resolution analog DVRs and automotive ADAS camera front-ends.
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, programmable CTI/sharpness/hue/saturation/brightness, dual I²S/DSP audio interface support, industrial temperature range (−40°C to +85°C), and time-multiplexed BT.656 output at 54/108 MHz or 72/144 MHz.
Technical Context
The PI7VD9008ABH implements eight independent analog video front-ends, each with proprietary clamp, AGC, and 5H comb filtering to separate luminance and chrominance while suppressing cross-color and cross-luminance artifacts across all NTSC/PAL variants. Its adaptive equalizer dynamically compensates for high-frequency loss in long coax runs without requiring external tuning.
Video digitization uses 10-bit ADCs per channel; decoded YCbCr data is formatted in ITU-R BT.656 time-multiplexed parallel output with selectable clock rates (54/108 MHz or 72/144 MHz). The integrated audio subsystem supports 10 analog inputs, one mixed analog output, and dual serial audio interfaces (I²S and DSP modes) 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 |
|---|---|---|---|
| ADV7180BCPZ | Single-channel SD decoder; no AEQ; max 2x D1 resolution; lacks 960H support and multi-channel BT.656 muxing | Requires 8× ICs for same channel count; higher BOM cost and PCB area; no coax compensation | Select only for low-channel-count legacy SD systems where AEQ and 960H are unnecessary |
| TCM8008A | 8-channel decoder with AEQ but no integrated audio codec; supports only NTSC; no PAL/960H compliance | Lacks audio processing capability; requires external audio ADC/DAC and mixing circuitry | Choose when audio is handled separately and PAL/960H support is not required |
Compared with ADV7180BCPZ and TCM8008A, the PI7VD9008ABH uniquely integrates full 8-channel 960H decoding, adaptive coax equalization, and 10-input audio codec in one LQFP package - reducing system component count, eliminating external audio mixing, and enabling single-chip HD analog DVR designs.

FAQ
What video standards does the PI7VD9008ABH support?
The PI7VD9008ABH supports NTSC(M), NTSC 4.43, and PAL standards including B, D, G, H, I, M, Nc, and 60. It fully complies with WD1/960H resolution requirements and delivers optimized decoding performance across all supported formats using its adaptive equalizer and 5H comb filter.
Does the PI7VD9008ABH require an external crystal oscillator?
Yes - it requires a 27 MHz fundamental-mode crystal connected between XTI and XTO pins. This crystal drives the internal video PLL, which generates precise 108 MHz or 144 MHz pixel clocks for BT.656 output, and supports NTSC, PAL, and 960H timing without external clock synthesis.
How many audio channels can be processed simultaneously?
The PI7VD9008ABH accepts up to 10 analog audio inputs (LINE_IN0 through LINE_IN9) and internally mixes them into a single low-noise analog output (AOUT). It also supports dual serial audio interfaces (I²S and DSP) for digital audio routing at sample rates from 8 kHz to 48 kHz.
Is the PI7VD9008ABH still in active production?
No - the PI7VD9008ABH is marked "OBSOLETE – PART DISCONTINUED" in official documentation. Aetrix Electronics maintains limited legacy inventory and supports design-in continuity through cross-reference guidance, last-time-buy planning, and migration paths to functionally aligned successors.
