Other Parts Discussed in Thread: LMH1218, TIDA-00428
Dear Team,
using lmh1219 and lmh1218 - i made a design for our 6G SDI transfer over SFP design same as TIDA-00428.
i able to make it work with receiving part lmh1218.
but unable to make it work with lmh1219.
in our lmh1219 design i made a mistake and connect VDD_LDO to 2.5V i done rework and able to make VDD_LDO as NC . i can read all internal status over I2C . Input IN0 successfully make lock at SDI input ,
but unable for transfer over SFP . i measure the optical strength using optical receiver measurement tool but it shows no transition .any idea what i can check in status res. for Output section of lmh1219? strange is i can measure Out signal as per VOD_DE strap option .
looking for your feedback.
