b. A power-on reset (POR) is both implemented at the transmitter and the receiver. It is active below V_{POR_DEACT}. Once V_{POR_DEACT}is reached,

the POR remains active for t_{POR-DEACT_DEL}. During power-down, POR starts at V_{POR_ACT}. During active POR, the output signal is low.

_{POR_DEACT}and V_{POR_ACT}both apply to Tx and Rx, t_{POR-DEACT_DEL POR}applies only for the Rx. The delay time of the Tx is typically ~10 µs.

etc.

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.
