Product details
Overview
ADV7160KS140 from Analog Devices is a 96-bit, 140 MHz true-color video RAM-DAC with triple 10-bit gamma-correcting DACs, integrated 64×64 hardware cursor, and on-board PLL. It serves as the core video output engine in high-resolution graphics subsystems, delivering 1600×1200×24-bit RGB analog outputs at 85 Hz refresh for professional imaging and digital TV applications.
For engineers reviewing the ADV7160KS140 datasheet, ADV7160KS140 pinout, ADV7160KS140 application, or ADV7160KS140 equivalent, this page provides verified specifications, validated pin functions, confirmed timing behavior at 140 MHz operation, and real-world integration context for Windows accelerators and HDTV signal chains.
Technical Context
The ADV7160KS140 implements a dual-path pixel data architecture: one path routes pixel data through 256×30 palette RAM before DAC conversion; the other bypasses RAM for direct pixel-to-DAC streaming-enabling per-pixel overlay of active video windows on graphics backgrounds. Its programmable pixel port supports 24-bit, 16-bit, 15-bit, and 8-bit pseudo-color formats via 2:1/4:1/8:1 multiplexing modes.
It integrates a fully programmable on-chip PLL referenced by a TTL-compatible 900 kHz–40 MHz input (PLLREF), generating precise pixel clocks up to 140 MHz. The device uses ECL-compatible differential CLOCK inputs and delivers RS-343A/RS-170-compliant analog outputs (IOR/IOG/IOB) with tri-level SYNC functionality and 2% max DAC-to-DAC color matching.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar video RAM-DAC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADV7162KS1404 | Same core architecture and 140 MHz speed grade, but packaged in standard 160-pin QFP (no heatsink) | Limited thermal headroom in sustained 140 MHz operation; unsuitable for compact, convection-cooled enclosures | Select ADV7162KS1404 only when board layout constraints prohibit PQUAD footprint or thermal mass is externally managed |
| ADV7125KSTZ140 | Triple 8-bit DAC (not RAM-DAC); no integrated palette, cursor, or PLL; requires external clock generation and memory | Targeted at simpler video DAC tasks without color lookup or overlay - lacks 24-bit true-color pipeline and programmable pixel port | Choose ADV7125KSTZ140 for cost-sensitive, non-graphics applications where palette-based color mapping is unnecessary |
Compared with ADV7162KS1404 and ADV7125KSTZ140, the ADV7160KS140 uniquely combines 140 MHz pixel throughput, on-die 256×30 palette RAM, and thermally robust PQUAD packaging - making it the only option that delivers full-featured true-color graphics acceleration without external support ICs or thermal derating.

FAQ
What is the maximum supported resolution and refresh rate for ADV7160KS140?
The ADV7160KS140 supports 1600×1200×24-bit resolution at 85 Hz screen refresh when operating at its rated 140 MHz pixel clock. This capability is confirmed in the "Modes of Operation" section of the datasheet and validated by timing parameters t1–t4 at the 140 MHz speed grade. The ADV7160KS140 achieves this using its 96-bit pixel port and triple 10-bit DAC architecture without interpolation or frame buffering.
Does ADV7160KS140 require an external voltage reference?
Yes, the ADV7160KS140 requires an external 1.235 V ±1.5% analog voltage reference applied to the VREF pin. The datasheet specifies that performance is guaranteed only when VREF = 1.235 V, and recommends using an AD589 or equivalent two-terminal reference. Using a resistor divider is explicitly discouraged due to stability and noise concerns affecting DAC accuracy.
How does the pixel port multiplexing work on ADV7160KS140?
The ADV7160KS140 implements 2:1, 4:1, or 8:1 multiplexing on its 96-bit pixel port (R0A–R7D, G0A–G7D, B0A–B7D) to accept 24-bit, 16-bit, 15-bit, or 8-bit pixel data formats. LOADIN frequency scales inversely with multiplex ratio (e.g., 70 MHz for 2:1 mode at 140 MHz CLOCK). Pin function descriptions confirm each bit group (A–D) is multiplexed, and timing tables specify t5–t7 values per mode for ADV7160KS140.
Can ADV7160KS140 generate tri-sync signals for HDTV applications?
Yes, the ADV7160KS140 supports tri-sync functionality via the TRISYNC input pin and associated Command Register 1 bit CR17. When TRISYNC is asserted low during blanking, DAC outputs transition to the tri-sync level (6.29–8.96 mA), meeting HDTV timing requirements. This is distinct from standard SYNC and is documented in the PIN FUNCTION DESCRIPTION and ANALOG OUTPUTS sections for ADV7160KS140.
What is the purpose of the RSET pin on ADV7160KS140?
The RSET pin on ADV7160KS140 sets the full-scale output current of the triple DACs by connecting an external resistor to analog ground. With VREF = 1.235 V and RSET = 280 Ω, the DAC gain is configured to 3996 - achieving RS-343A sync+pedestal compliance (17.62 mA white level). The datasheet provides a calculation formula and confirms RSET's direct impact on IOR/IOG/IOB amplitude in the ADV7160KS140 specifications table.
