b. A power-on reset (POR) is both implemented at the transmitter and the receiver. It is active below VPOR_DEACT. Once VPOR_DEACT is reached,
the POR remains active for tPOR-DEACT_DEL. During power-down, POR starts at VPOR_ACT. During active POR, the output signal is low.
V
POR_DEACT and VPOR_ACT both apply to Tx and Rx, tPOR-DEACT_DEL POR applies only for the Rx. The delay time of the Tx is typically ~10 µs.

Data_in
A low Input signal at Data_in results in a low output signal at Data_out (non-inverted Tx to non-inverted Rx).
POR remains active during VCC power up, typically until 10 µs for Tx and 10ms for Rx after 2.8V is reached. For both Tx
and Rx, Data_out is low while POR active.
Recommended chemicals for Cleaning/Degreasing
Alcohols: methyl, isopropyl, isobutyl.
Aliphatics: hexane, heptanes
Other: soap solution, naphtha
Do not use partially halogenated hydrocarbons, such as 1.1.1 trichloroethane; or ketones, such as MEK, acetone,
chloroform, ethyl acetate, methylene dichloride, phenol, methylene chloride, or N-methylpyrolldone. Also, Broadcom does
not recommend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm.
