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
- Very low programming time: < 500ns for delay profile update
- 32-bit Checksum feature to detect wrong SPI writes
Internal temperature sensor and automatic thermal shutdown
No specific power sequencing requirement
Error flag register to detect multiple faulty condition
Integrated passives for the floating supplies and bias voltages
Small package: FCCSP-196 (12mm × 12mm) with 0.8mm pitch
