Detailed Specifications

STV0674

12/35

Note: 1 VDI = |(D+) - (D-)|

2VCM includes VDI range.

3 These figures apply to sfp, sensor_clk, sensor_scl, sensor_sda, test_mode and sensor_db. They do

not apply to the XTAL_IN pad, these are specified separately.

4 In normal operation the actual device operating voltage is the worst case figure of the PLL and Core

supplies, or 1.60V to 1.95V.

5 Below measurable limits.
