Device Overview

Summary

CW01 is a four-channel, low phase noise, continuous wave transmit 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. 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. Both VDD and VLL have undervoltage lockout to prevent spurious turn-on.

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...
