The X98027 275MHz Triple Video Digitizer with Digital PLL
The X98027 is a 3‑channel, 8‑bit analog front‑end video digitizer that converts RGB or YUV graphics signals from PCs, workstations, and set‑top boxes. It features a digital PLL that generates a pixel clock from HSYNC or SOG signals, supporting resolutions up to QXGA at 60 Hz.
Key features include a 275 MSPS conversion rate, programmable input bandwidth, automatic black‑level compensation, and a 128‑lead MQFP package. The document lists electrical specifications, pin assignments, serial‑bus interface details, and recommended operating conditions for designers.

The X98027 can convert video signals at up to 275 MSPS per channel.
It accepts video input voltages from 0.35 V to 1.4 V peak‑to‑peak.
The PLL can output pixel clocks from 10 MHz up to 275 MHz.
All supply rails (analog, digital, crystal) operate at 3.3 V.
