2025-06-10 11:10:52
Product Overview
The SII164CTG64 (SiI 164) is a single-link, DVI 1.0-compliant PanelLink™ digital video transmitter supporting pixel clocks from 25 MHz up to 165 MHz—perfect for resolutions ranging from VGA to UXGA. It features a flexible 12-bit or 24-bit input bus, selectable single/double-clock and single/double-edge data latching, and an I²C-programmable interface for dynamic configuration, enabling rapid system development and reduced BOM costs .
Key Features
-
Wide Bandwidth Range: 25 MHz to 165 MHz pixel clock supports a variety of resolutions.
-
Flexible Input Modes: Choose between 12-bit (½ pixel per clock edge) or 24-bit (1 pixel per clock) input; selectable single/double-clock and single/double-edge latching.
-
I²C Programmability: Up to 100 kHz allows register-level control of de-skew, clock edge, bus width, hot-plug detect, and more.
-
Ultra-Low Power: Typical supply current is 854 mA (3.3 V); peaks at 1 205 mA. Power-Down mode draws ≤1 mA.
-
Hot-Plug and Receiver Detection: HTPLG input pin and RSEN register output support external hot-plug and internal receiver status monitoring.
-
DVI 1.0/ DVI-DL Backward Compatibility: Complies with VESA® P&D and DFP standards for broad display support.
-
Adjustable TMDS Swing: External resistor on EXT_SWING pin tailors differential output amplitude for different cable lengths and environments.

Design & Layout Recommendations
-
I²C Level Shifting: Use dual-direction level translators (e.g., NDC7002N, GTL2010) when interfacing with 1.5 V I²C hosts to ensure reliable 3.3 V communication.
-
TMDS Swing Tuning: Place a 510 Ω – 680 Ω precision resistor on EXT_SWING for optimal signal integrity and minimal EMI.
-
Decoupling Capacitors: Deploy 100 pF + 2.2 µF + 10 µF networks close to each VCC pin to minimize supply noise.
-
Differential Routing: Maintain 100 Ω differential impedance with tight pair routing to reduce skew and crosstalk.
-
Series Damping Resistors: Add 22 Ω – 33 Ω at source pins to suppress reflections and improve EMI performance.
