Product details
Overview
AD9983AKCPZ-140 from Analog Devices is a monolithic 8-bit, 140 MSPS triple analog-to-digital converter optimized for RGB/YPbPr video digitization in display interface systems. It integrates three matched ADCs, an internal PLL clock generator (10–140 MHz), auto-offset and auto-gain calibration, and programmable output formatting (4:4:4, 4:2:2, DDR). It supports HDTV up to 1080i/720p and SXGA graphics (1280 × 1024 @ 75 Hz) with full-power analog bandwidth of 300 MHz.
For engineers reviewing the AD9983AKCPZ-140 datasheet, AD9983AKCPZ-140 pinout, AD9983AKCPZ-140 application, or AD9983AKCPZ-140 equivalent, key selection criteria include its 140 MSPS sampling rate, triple-channel gain/offset matching capability, 300 MHz analog bandwidth, 80-lead LQFP package, and support for sync-on-green, tri-level sync, and external clock/coast modes.
Technical Context
The AD9983AKCPZ-140 implements three independent 8-bit ADC channels with fully integrated PGA, clamp circuitry, and reference buffers - each supporting 0.5–1.0 Vp–p analog inputs. Its on-chip PLL generates a low-jitter pixel clock from HSYNC, VSYNC, or SOG inputs, with 32-step phase adjustment and coast mode for uninterrupted clocking during vertical blanking.
Digital control is handled via a 2-wire I²C-compatible serial port (SDA/SCL), enabling real-time configuration of gain, offset, clamp timing, output drive strength, sync polarity, field detection, and data format (including odd/even field flag and regenerated HSOUT/VSOUT). All outputs are 3-state CMOS, configurable for 1.8 V or 3.3 V logic levels.

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog video digitizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9983AKCPZ-135 | Rated for 135 MSPS max conversion rate; identical pinout, register map, and feature set. | Suitable for lower-resolution displays (e.g., XGA, WXGA) where 140 MSPS headroom is unnecessary. | Select when system pixel clock ≤135 MHz to allow margin for thermal derating or cost-sensitive sourcing. |
| AD9984AKCPZ | 10-bit resolution, 135 MSPS, same 80-lead LQFP package and I²C interface; lacks SOGIN/SOGOUT pins. | Targeted at higher-fidelity graphics acquisition where bit depth outweighs sync-on-green flexibility. | Choose for applications requiring >8-bit color depth (e.g., medical imaging, digital signage) and no SOG processing. |
Compared with AD9983AKCPZ-140, the -135 variant offers identical functionality at reduced speed for cost-optimized designs, while the AD9984AKCPZ trades SOG capability for 2 extra bits of resolution - making it suitable for precision graphics but incompatible in SOG-dependent video systems.

FAQ
What is the maximum supported pixel clock frequency for AD9983AKCPZ-140?
The AD9983AKCPZ-140 supports a maximum conversion rate of 140 MSPS, enabling pixel clock frequencies up to 140 MHz. This allows full support for HDTV standards including 1080i and 720p, as well as SXGA graphics (1280 × 1024 at 75 Hz). The on-chip PLL maintains stable lock across this range with low jitter performance.
Does AD9983AKCPZ-140 support sync-on-green (SOG) input processing?
Yes, AD9983AKCPZ-140 includes dedicated SOGIN0 and SOGIN1 inputs with an internal high-speed comparator and programmable 8-mV threshold (8–256 mV above negative peak). It outputs processed sync via SOGOUT, selectable among raw SOG, raw Hsync, or filtered variants using Register 0x1D. This eliminates need for external sync separators in SOG-based systems.
How does the auto-offset calibration function in AD9983AKCPZ-140?
The AD9983AKCPZ-140's auto-offset feature dynamically restores signal reference levels by measuring and correcting DC offsets in each of the three ADC channels (R/G/B or Y/Pb/Pr). It operates during blanking intervals and can be enabled via serial register control, ensuring consistent black-level tracking across temperature and aging - critical for stable color reproduction.
What power supply voltages does AD9983AKCPZ-140 require?
AD9983AKCPZ-140 requires four separate supplies: VD = 1.8 V (analog core), VDD = 1.8–3.3 V (digital outputs), PVD = 1.8 V (PLL), and DAVDD = 1.8 V (digital logic). Each has defined absolute maximum ratings (e.g., VD ≤ 1.98 V) and specified current draws (ID = 250 mA, IDD = 31 mA, etc.), necessitating independent filtering and low-noise regulation.
Is AD9983AKCPZ-140 pin-compatible with other members of the AD9983 family?
Yes, AD9983AKCPZ-140 shares identical 80-lead LQFP pinout, register map, and functional interface with AD9983AKCPZ-135 and AD9983AKCPZ-110. Differences are limited to maximum sampling rate and associated AC specifications - allowing drop-in replacement in designs where speed margin permits, without PCB or firmware changes.
