Part Number: LMK04832EVM
Hi Tech,
PN#LMK04832EVM
1pcs from PO#029-FY977 with D/C 2545 & Lot Code 5021665SVT
Our customer has encountered an issue during operation: out of its14 channels, 6 channels are producing no signal output, and 2 channels support only LVDS output while failing to support LVPECL output.
This screenshot shows Channel 5. It is supposed to provide an LVDS output with a peak-to-peak voltage (Vpp) of 400 mV. The yellow trace displays the signal output at the SMA connector after AC coupling, while the blue trace shows the direct output from the chip itself—probed prior to the AC coupling stage. The signal consists solely of a 3.3 V DC component, with no discernible 40 MHz AC output.
Could you please help me identify the cause of this issue? Thank you.
