The X98027 is a 275MHz triple video digitizer with digital PLL from Intersil. It supports RGB and YUV formats, and provides high PSRR and dynamic performance to meet the stringent requirements of the graphics display industry.
The X98027 is a 3‑channel, 8‑bit analog front‑end video digitizer designed to convert analog RGB or YUV graphics signals from PCs, workstations and set‑top boxes. It offers a fully differential design with high PSRR and dynamic performance, supporting resolutions up to QXGA at 60 Hz.
Key features include a 275 MSPS conversion rate, programmable input bandwidth (100 MHz‑780 MHz), automatic black‑level compensation, a digital PLL with pixel‑clock output from 10 MHz to 275 MHz, and integrated voltage regulators for single‑supply operation.
| Maximum conversion rate per channel | 275 MSPS |
|---|---|
| Input voltage range | 0.35 Vpp – 1.4 Vpp |
| PLL clock jitter | 250 ps peak‑to‑peak |
| Typical power dissipation | 1.2 W |
| Analog supply voltage (Va) | 3.3 V (3.0 V‑3.6 V range) |
| Digital output HIGH voltage | 2.4 V (Io = 16 mA) |
Each channel can convert at up to 275 MSPS.
The analog and digital supplies operate from 3.0 V to 3.6 V, with a typical value of 3.3 V.
