CW01
4-Channel Low-Phase-Noise Low-Power Continuous Wave Transmitter
Features General Description The CW01 is a 4-channel low-phase-noise continuous
wave transmitter IC. A high-speed D flip-flop is
provided to allow the DIN frequency to be aligned to a
high-frequency clock. The output N-channel is turned
on when a logic high is clocked into the D flip-flop. Data
are clocked-in during the low-to-high transition. Low Phase Noise
100V Open Drain N-channel
High-speed D Flip-flop
High-speed MOSFET Gate Driver
Up to 200 MHz Clock Input
VDD and VLL Undervoltage Lockout VD1, VD2, VD3 and VD4 are four individual input supply
voltages for the N-channel output MOSFET gate
drivers. High peak currents are drawn from these gate
drives when the output MOSFETs are switching. To
minimize jitter caused by voltage ripples, each channel
has its own gate drive voltage pin—VD1, VD2, VD3 and
VD4. A series ferrite bead and a decoupling capacitor
are recommended on each VDX pin to minimize output
jitter and channel-to-channel crosstalk. Applications Diagnostic Medical Ultrasound Fluid Flow Measurement Both VDD and VLL have undervoltage lockout to
prevent spurious turn-on. Package Type PGND1 VD2 VD1 VSS OE 24-lead QFN
