LMX2487E EVM
USB2ANY Q1
Your mentioned Table 3 is snau137a page 35 ?
I followed that, and got DATA/CLOCK/LE seems correctly.
CLK=8
DATA=4
LE =2
CE=10
ENOSC=7
TRIGGER=1

2. Regardless of here, Ftest/LD stays low
C3:C0= 1001 (REG4)
DATA
CLOCK LE
Ftest/LD ( stay low…..)
I change here to
“Logic High” but
Ftest/LD stays low

3. Q2
Is there any sequence ( order ) to program register R4 ?
For example, R4 should be programmed after R0~R3 were programmed…?
For example, Power OFF(CE=L) and power ON to reset all registers..?
Otherwise I doubt my LMX2487E EVM may broken…

4. Our ( customer’s) goal is to have Q3
Our ( customer’s) goal is to have
Fin_RF=450MHz input  (1/384) RF_N/2 divider  output 1.17MHz to Ftest/LD pin.
(Before they had been used MB15F72UL(Fujitsu) but its EOL, so customer design using LMX2485E now)
We have no LMX2485E EVM so, evaluating LMX2487E EVM and we will replace it to LMX2485E.
I believe above is achieved for LMX2485E,but would you please confirm again?
If yes , which is better to select RF_P= 0 or RF_P=1, both of RF_P=0 or 1 is Okay ??
1.17MHz
450MHz
