I am confuse with the fuction with R5 register's DB29.what is mean when it is set to 1.Does it means Tx Data Pin Output the ramp clk set with clk1 and clk2?
when it is set to 0 ,what's that mean?
When R5 = 1 the internal ramp clock is bypassed and each step triggered by a pulse on the txdata pin. The following scope captures the txdata signal on the top trace and the VCO Vtune signal on the bottom trace for a sawtooth ramp. When R5=0 the ramp step time is set via CLK1 (R2[14:3]) and CLK2 (R4[18:7]) registers as shown in datasheet EQ8.
Thank You So So Much!
