The AD9880 is a high-performance HDMI/DVI dual display interface chip that supports both HDMI and DVI interfaces and supports high-bandwidth digital content protection.
The AD9880 is an 8‑bit, 150 MSPS dual‑interface chip that combines an analog video front‑end with an HDMI/DVI receiver on a single device. It supports high‑bandwidth digital content protection (HDCP 1.1) and provides both RGB and YCbCr output formats for HDTV, projectors and LCD monitors.
Key specifications include a 330 MHz analog bandwidth, pixel‑clock generation from 12 MHz to 150 MHz, 1.8 V/3.3 V power supplies, and a 100‑lead LQFP Pb‑free package. The datasheet provides detailed electrical characteristics, pin configurations, and design guidelines for integration.
| Resolution | 8 bits |
|---|---|
| Maximum Conversion Rate | 150 MSPS |
| Analog Bandwidth | 330 MHz |
| Pixel Clock Range | 12 MHz – 150 MHz |
| HDMI Receiver Standard | HDMI 1.1, DVI 1.0 |
| Package | 100‑lead LQFP Pb‑free |
| Supply Voltage (Vop) | 3.15 V – 3.47 V |
| Supply Voltage (DVpp) | 1.8 V – 1.9 V |
The device needs 1.8 V or 3.3 V analog power supplies, with separate digital supply rails; typical Vop is 3.3 V and DVpp is 1.8 V.
The on‑chip PLL can generate pixel clocks from 12 MHz up to 150 MHz.
It is supplied in a 100‑lead LQFP Pb‑free surface‑mount package.
