Product details
Overview
TVP3026-220PCE from Texas Instruments is a 64-bit video interface palette (VIP) IC designed for high-resolution graphics systems, supporting true-color packed-24 modes up to 1600 × 1280 @ 76 Hz, with integrated triple 8-bit DACs, three programmable PLLs (pixel, memory, loop), and on-chip 64 × 64 hardware cursor. It directly drives doubly terminated 75-Ω video lines and interfaces natively with VRAM and graphics accelerators.
For engineers reviewing the TVP3026-220PCE datasheet, TVP3026-220PCE pinout, TVP3026-220PCE application, or TVP3026-220PCE equivalent, key selection criteria include pixel clock capability (220 MHz), packed-24 timing compliance, VGA pass-through support, analog output full-scale adjustability, and register-level compatibility with TVP3020/INMOS IMSG176/Brooktree Bt476.
Technical Context
The TVP3026-220PCE implements a dual-ported 3×256×8 color palette RAM with triple 8-bit current-output DACs, enabling simultaneous palette read/write and video output. Its pixel clock PLL delivers a 50% duty cycle reference clock optimized for VRAM cycle efficiency in packed-24 mode.
It integrates three independent clock synthesis blocks: a pixel clock PLL (220 MHz max), a memory clock PLL (14–100 MHz), and a loop clock PLL for latch timing compensation. The device supports little/big-endian data format, 4/8/12/16/24-bit pixel formats, and hardware-accelerated color-key and port-select switching for overlay composition.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Pixel Clock | 220 MHz - enables 1600×1280 @ 76 Hz true-color display without external clock generation |
| Pixel Bus Width | 64-bit - supports packed-24 pixel transfer at full resolution without bus bottlenecks |
| DAC Resolution | Triple 8-bit - provides 256 levels per RGB channel for gamma-corrected analog video output |
| PLL Count | Three independent PLLs - pixel, memory, and loop clock PLLs eliminate need for external clock ICs |
| Hardware Cursor | 64×64×2 - XGA- and X-Window-compatible on-chip cursor reduces CPU load and frame buffer bandwidth |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video interface palette applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TVP3026-175PCE | Lower max pixel clock (175 MHz); identical pinout, register map, and feature set | Supports up to 1280×1024 @ 75 Hz; insufficient for 1600×1200 @ 76 Hz | Select when target resolution is ≤1280×1024 and cost optimization is prioritized over peak bandwidth |
| TVP3026-135PCE (Rev A) | 135 MHz max pixel clock; limited to earlier revision with known errata in loop PLL lock stability | Not qualified for high-refresh-rate packed-24 modes; requires additional board-level PLL validation | Only consider for legacy repair or low-cost VGA-only applications where 220 MHz capability is unused |

FAQ
What is the maximum supported resolution and refresh rate for TVP3026-220PCE?
The TVP3026-220PCE supports up to 1600 × 1280 resolution at 76 Hz refresh rate in true-color packed-24 mode. This capability is enabled by its 220 MHz pixel clock and 64-bit pixel bus architecture, which eliminates memory bandwidth constraints seen in lower-clock variants like TVP3026-175PCE.
Does TVP3026-220PCE require external DACs or clock synthesizers?
No. The TVP3026-220PCE integrates triple 8-bit current-output DACs capable of driving doubly terminated 75-Ω lines directly, and three fully programmable PLLs (pixel, memory, loop) - eliminating the need for external DACs, clock ICs, or phase-compensation circuitry in most graphics designs.
How does the loop clock PLL in TVP3026-220PCE improve system timing reliability?
The loop clock PLL in TVP3026-220PCE dynamically compensates for PCB trace delays and voltage/temperature drift, ensuring precise pixel data latching timing. Unlike fixed-delay solutions, it maintains setup/hold margins across operating conditions - critical for stable 220 MHz operation in packed-24 mode.
Is TVP3026-220PCE software compatible with earlier VIP devices?
Yes. The TVP3026-220PCE maintains full register-level compatibility with TVP3020 and is software compatible with INMOS IMSG176/8 and Brooktree Bt476/8 palettes. This allows reuse of existing driver firmware and simplifies migration from legacy VIP designs.
What package type and pin count does TVP3026-220PCE use?
The TVP3026-220PCE uses a 160-pin Plastic Quad Flat Pack (PQFP) package designated by the suffix "PCE". Pin assignments match the TVP3026 family datasheet SLAS098B, including dedicated AVDD/DVDD/PLLVDD power domains and four selectable clock inputs (CLK0/CLK1/CLK2/CLK2).
