Product details
Overview
AD9883ABSTZ-RL140 from Analog Devices is an 8-bit, 140 MSPS triple analog-to-digital converter 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, programmable clamp/gain/offset, and PLL-based pixel clock generation (12–140 MHz) with 500 ps p-p jitter at 140 MSPS. It supports SXGA (1280 × 1024 @ 75 Hz) in LCD monitors and digital projectors.
For engineers reviewing the AD9883ABSTZ-RL140 datasheet, AD9883ABSTZ-RL140 pinout, AD9883ABSTZ-RL140 application, or AD9883ABSTZ-RL140 equivalent, this page delivers verified technical context, exact pin functions, real-world timing relationships (DATACK/HSOUT/data alignment), industrial-grade thermal specs (–40°C to +85°C), and validated alternatives for flat-panel video front-end design.
Technical Context
The AD9883ABSTZ-RL140 implements three independent 8-bit ADCs with internal clamping, gain, and offset control per channel-each configurable via 2-wire serial interface registers. Its PLL derives pixel clock from HSYNC input, maintains frequency during COAST assertion, and supports phase adjustment while preserving data-clock-sync timing integrity.
It features full sync processing for composite sync and sync-on-green (SOGIN) inputs, with programmable SOG threshold (10–330 mV), internal midscale clamping (MIDSCV pin), and 3.3 V CMOS outputs compatible with 2.5–3.3 V logic. All analog inputs accept 0.5–1.0 Vp-p ac-coupled signals, and digital inputs are 5 V tolerant.

Pinout & Package
AD9883ABSTZ-RL140 is housed in an 80-lead LQFP (ST-80) package with exposed thermal pad, optimized for thermal dissipation (θJA = 35°C/W) in space-constrained display controller PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog video interface applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9884ABSTZ-140 | 10-bit resolution, 140 MSPS, same 80-lead LQFP package, identical pinout and serial interface | Higher dynamic range (SNR ≈ 52 dB vs. 43 dB) suits medical imaging or color-critical graphic workstations | Select when >8-bit fidelity is required; software-compatible but requires updated driver calibration tables |
| THS8200IPHP | Triple 10-bit ADC, 170 MSPS, integrated sync separator, no internal PLL; requires external clock source | Lacks COAST mode and SOG processing; better suited for fixed-clock broadcast video systems than PC graphics | Choose for broadcast infrastructure where external clock distribution is already present and SOG is unused |
Compared with AD9883ABSTZ-RL140, AD9884ABSTZ-140 offers higher resolution at identical speed and footprint, while THS8200IPHP trades integrated clock generation for higher sample rate and dedicated sync separation-making each suitable for distinct signal-source ecosystems.

FAQ
What is the maximum pixel clock frequency supported by the AD9883ABSTZ-RL140?
The AD9883ABSTZ-RL140 supports a maximum PLL clock rate of 140 MHz, enabling capture of resolutions up to SXGA (1280 × 1024) at 75 Hz. This 140 MSPS conversion rate is guaranteed over the full –40°C to +85°C operating range and is validated in the AD9883ABST–140 specification table under "Maximum Conversion Rate" and "Maximum PLL Clock Rate."
Does the AD9883ABSTZ-RL140 support sync-on-green (SOG) signals?
Yes, the AD9883ABSTZ-RL140 supports SOG via the SOGIN input pin and SOGOUT output pin. The internal comparator threshold is programmable in 10 mV steps from 10 mV to 330 mV above the negative signal peak, with a default of 150 mV. This allows reliable extraction of composite sync from the green channel without external circuitry.
What power supply voltages does the AD9883ABSTZ-RL140 require?
The AD9883ABSTZ-RL140 requires three separate supplies: VD = 3.0–3.6 V (analog core), VDD = 2.2–3.6 V (digital outputs, compatible with 2.5 V logic), and PVD = 3.0–3.6 V (PLL circuitry). Each supply must be independently decoupled, and the datasheet specifies distinct current draws: ID ≈ 163 mA, IDD ≈ 24 mA, IPVD ≈ 10 mA at 25°C.
Can the AD9883ABSTZ-RL140 perform midscale clamping for YUV signals?
Yes, the AD9883ABSTZ-RL140 supports midscale clamping via the MIDSCV pin (Pin 37) and dedicated clamp-select bits in register 10H (Bits 0–2). When enabled, each ADC clamps to the midscale reference voltage (≈1.25 V) instead of ground, making it suitable for YUV or other midscale-referenced analog video formats.
Is the AD9883ABSTZ-RL140 pin-compatible with earlier AD9883 variants?
Yes, the AD9883ABSTZ-RL140 shares identical pinout, package (80-lead LQFP ST-80), and electrical characteristics with all AD9883A variants including AD9883ABST-140 and AD9883AKSTZ-140. The "Z" suffix denotes lead-free finish, and "RL" indicates tape-and-reel packaging-both are drop-in replacements for board-level compatibility.
