4.7 SFP AC parameters

Each SFP is a TTL schmitt trigger bidirectional pad Buffer, 3v3 capable with 2mA drive capability

and Slew-rate Control. The 3.3V IOs comply to the EIA/JEDEC standard JESD8-B. For sake of

convenience the most important parameters for measurement have been extracted and presented

below.

Note: 1 The above timings assume that the sensor_clk load is 20pF.

2 The sensor data setup and hold times are requirements of the STV0674.

3 tAC represents the maximum allowed clock to data delay from STV0674 sensor_clk pad to the

STV0674 sensor data pads. (i.e. STV0674 pad to sensor PCB delay + sensor clock to data delay +

sensor data pad to STV0674 pad PCB delay).
