  • 8-Channel transmitter, each channel includes:
    • 5-level pulser with on-chip beamforming
    • Active T/R switch
    • Integrated floating supplies
  • 5-Level Pulser supports:
    • Maximum output voltage: ±100V
    • Minimum output voltage: ±1V
    • Maximum output current: 2A
    • Support 4A output current mode
    • True return to zero to discharge to ground
    • Second harmonic of –45dBc at 5MHz
    • –3dB Bandwidth with 220Ω || 240pF load
      • –20MHz for a ±100V supply
      • 35MHz for a ±100V supply in 4A
    • Integrated jitter: 100fs from 100Hz to 20kHz
    • CW mode close-in phase noise: –154dBc/Hz at 1kHz offset for 5MHz signal
  • Active T/R switch with:
    • Turn ON resistance: 8Ω
    • Turn ON and OFF time: 300ns
    • Channel based T/R switch on and off controls
  • On-chip beamformer for pulser with:
    • Channel based T/R switch on and off controls
    • Delay resolution: Half beamformer clock period, minimum 1.56ns
    • Maximum delay: 214 beamformer clock period
    • Per channel 960 × 32 bits memory to store waveform and delay values.
  • High-speed (400MHz maximum), 2-lane LVDS serial programming interface
