CW01DB1
4-Channel, Low Phase Noise,
Low Power, Continuous Wave Transmitter
General Description
The CW01 has 6 logic inputs; OE, CLK, DIN1, DIN2, DIN3,
and DIN4. Every logic input has a 10kΩ pull down resistor.
There are 3 power input voltages: VLL, VDD and VDX. VLL is the
input logic level, typically 2.5V. VDD is the level translator,
typically 5.0V. VDX is the gate drive voltage, and is at the
same voltage level as VDD. High peak currents will be
drawn from VDX during switching. Each supply has a series
ferrite bead and a 0.1µF ceramic chip capacitor to keep the
supply clean from high frequency noise.

There are 4 outputs: HV1, HV2, HV3 and HV4. These are
the connections to the drains of 100V, 7.0Ω, N-channel
MOSFETs.
