Part Number: FPC401 Hi, I noticed that the FPC401 addresses the downstream device when accessing pre-fetched SFP data. This results in stretching the host side I2C clock (first two bytes). I'm attaching a screen grab from an I2C analyzer showing this…
Part Number: FPC401 Hi team,
Could you help explain how FPC401 will detect the LOS signal and generate Interrupt output? Any debouncing operation included?
Also, pls help to check below application OK or not? We will use many LOS signals input. IN_B is…
Part Number: FPC401 Other Parts Discussed in Thread: FPC402 , Hello,
Customer has one more question about FPC401 and FPC402. Except i2c downstream address diff as below, Did FPC401 and FPC402 has other diff features or limitations on application? I could…
Hi Levin,
Levin wang said: Just as your suggestion, we adjust the period parameter with more length of time than reading bytes time on periodic prefetch mode. The RX LOS alarm received correctly now.
Glad you were able to resolve this issue.
If you use…
Part Number: FPC401 Other Parts Discussed in Thread: FPC402 , Hi team,
I have a question below need your help:
Are FPC401 and FPC402 I2C mode able to support access of QSFP-28 and QSFP-DD EEPROM full address range?
In the FPC402 applications QSFP-DD is…

Hi team,
We want to check the difference between the FPC401 and FPC402. Thanks.
How to deal with the unused GPIO,SPI_LED_CLK, ports(ports related pins as ABS, TXFAULT)? Whether we can float? Thanks…
Part Number: FPC401 Hi,
We're looking to use the FPC401 on our design and looking at the data sheet the device powers up with a default address of 0x1E in 8bit, (0xF in 7bit). Also, the down stream devices are placed at 0xF0 0xF2 0xF4 0xF6 0xF8 0xFA…

Hi Team,
FPC401 could control maximum 4 LEDs, 2 could control blinking and dimming and the other 2 are ON/OFF only, right?
how about FPC202 and FPC402?
Part Number: FPC401 Other Parts Discussed in Thread: FPC402 Posted on behalf of another E2E user:
For the optical module I2C address, do we have only two choices for 8-bit address: 0xA0 & 0xA2? If the optical module has some other I2C address (like 0x04…
Part Number: FPC401 Hi,
Our customer is considering FPC401. Then, if the SFP+/QSFP+ is stuck during I2C communications, is there any way to reset the SFP+/QSFP+?
Best Regards,
