Product details
Overview
AD9883ABSTZ-140 from Analog Devices is an 8-bit, 140 MSPS triple analog-to-digital converter IC optimized for RGB graphics capture in flat-panel display interfaces. It integrates a 300 MHz full-power analog bandwidth, on-chip 1.25 V reference, PLL-based pixel clock generation (12–140 MHz), and programmable clamp/gain/offset control. It supports SXGA (1280 × 1024 @ 75 Hz) resolution in LCD monitors and digital projectors.
For engineers reviewing the AD9883ABSTZ-140 datasheet, AD9883ABSTZ-140 pinout, AD9883ABSTZ-140 application, or AD9883ABSTZ-140 equivalent, key selection criteria include its 140 MSPS conversion rate, 500 ps p-p PLL jitter at max rate, industrial temperature range (–40°C to +85°C), 3.3 V single-supply operation, and 80-lead LQFP package with validated RGB/HSYNC/VSOUT/SOGOUT timing alignment.
Technical Context
The AD9883ABSTZ-140 implements three independent 8-bit ADC channels with matched input paths for R/G/B analog signals, each accepting 0.5–1.0 Vp-p ac-coupled inputs. Its internal PLL derives pixel clock from HSYNC with ±15 ps/°C sampling phase tempco and maintains frequency during COAST mode.
Sync processing includes composite sync detection, sync-on-green slicing (programmable 10 mV threshold), and fully reconstructable HSOUT/VSOUT outputs phase-aligned to DATACK. All digital I/Os are 3.3 V CMOS with 5 V tolerance, and configuration occurs via a 100 kHz max 2-wire serial interface (SDA/SCL/A0).

FAQ
What is the maximum supported resolution for AD9883ABSTZ-140?
The AD9883ABSTZ-140 supports resolutions up to SXGA (1280 × 1024) at 75 Hz, enabled by its 140 MSPS maximum conversion rate and 300 MHz analog bandwidth. This allows full pixel capture without undersampling or aliasing in standard PC graphics timings. The AD9883ABSTZ-140 achieves this using internal PLL-generated pixel clocks ranging from 12 MHz to 140 MHz, with phase alignment maintained across DATACK, HSOUT, and RGB data outputs.
Does AD9883ABSTZ-140 support sync-on-green (SOG) signals?
Yes, AD9883ABSTZ-140 includes dedicated SOGIN and SOGOUT pins with a programmable comparator threshold (10–330 mV above negative peak). The SOG slicer output appears on SOGOUT either as processed sync data or as a delayed HSYNC signal, depending on register configuration. This capability is confirmed in the functional block diagram and PIN FUNCTION DESCRIPTIONS section of the AD9883ABSTZ-140 datasheet.
What power supplies does AD9883ABSTZ-140 require?
The AD9883ABSTZ-140 requires three independent 3.3 V supplies: VD (analog core), VDD (digital outputs, configurable down to 2.5 V), and PVD (PLL circuitry). Each has dedicated pins and ground return paths to isolate noise-VD powers the ADCs and reference, VDD drives the 24-bit RGB bus and DATACK/HSOUT, and PVD supplies the sensitive PLL filter node (FILT, Pin 33). Total typical dissipation is 700 mW.
Can AD9883ABSTZ-140 operate in power-down mode?
Yes, AD9883ABSTZ-140 features a hardware-controllable power-down mode that reduces supply current to 5–15 mA and total dissipation to 16.5–33 mW. Entry is controlled via the serial interface (register 0FH, Bit 0), and all outputs enter high-impedance state. Recovery time is specified as tBUFF = 4.7 µs, enabling rapid wake-up for dynamic power management in portable or energy-sensitive display systems.
Is AD9883ABSTZ-140 RoHS-compliant and lead-free?
Yes, AD9883ABSTZ-140 is a lead-free, RoHS-compliant device indicated by the "Z" suffix in the part number. It uses matte tin lead finish and meets JEDEC J-STD-020 moisture sensitivity level 3 (MSL-3) requirements. The ordering guide confirms AD9883ABSTZ-140 as a lead-free product, and the package is an 80-lead LQFP (ST-80) with exposed pad for thermal performance.
