• Double window Picture-In-Picture (PIP) in interlaced or non-interlaced mode at 8-bit resolution

• Internal 1-Mbit DRAM

• Three 8-bit Analog-to-Digital Converters (ADCs) (7-bit performance) with clamp circuit for each acquisition channel

• One PLL which generates the line-locked clocks for the subchannel

• One PLL which generates the line-locked clocks for the main and display channels

• Three 8-bit Digital-to-Analog Converters (DACs)

• Linear zoom in both horizontal and vertical directions for the subchannel

• Linear zoom in horizontal direction for the main channel.
