LMX2433EVAL: Time until the PLL locks

ACGUY

Part Number: LMX2433EVAL
Other Parts Discussed in Thread: LMX2433, USB2ANY

Hello E2E,

Our customer has plan to use the EVM for time measurement until the PLL locks.
However, the LMX2433 has not trigger register.
Please let me know the start point and end point (point is mark or flag) for time until the PLL locks.

Regards,

Hi Acguy,

you can use the rising edge of the LE signal to trigger the test equipment and use the LD pin to look for PLL locks.

Hi Acguy,

LE is one of the SPI (or uWIRE) signals, which is supported by USB2ANY.
