• Sampling rate up to 55 MHz
• −3 dB bandwidth of 190 MHz
• 5 V power supplies
• Binary or twos-complement CMOS outputs
• In-range CMOS-compatible output
• TLL-CMOS compatible static digital inputs
• 3 to 5 V CMOS-compatible digital outputs
• Differential clock input; Positive Emitter Coupled Logic (PECL)-compatible
• Power dissipation 325 mW (typical)
• Low analog input capacitance (typical 2 pF), no buffer amplifier required
• Integrated sample-and-hold amplifier
• Differential analog input
• External amplitude range control
• Voltage controlled regulator included.
