Notes:
1. CL = 15p, RL = 50kOhm F
2. 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.
VPOR_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 ~10µs.

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, ketones such as MEK, acetone, chloroform,
ethyl acetate, methylene dichloride, phenol, methylene chloride, or N-methylpyrolldone. Also, Avago does not recom-
mend the use of cleaners that use halogenated hydrocarbons because of their potential environmental harm.
A low Input signal at Data_in results in a low output signal at Data_out.
POR remains active during VCC power up, typically until 10µs for Tx and 10ms for Rx after 2.8V is reached. For both Tx and
Rx Data_out is low while POR active.
Specied Link Performance, TA = -40°C to +85°C, DC to 5MBaud, unless otherwise noted.

Notes:
1. Provided the following characteristics of the electrical input:
a) no PWD at 1.5V input level
b) dU/dt between 1V and 2V is less than 1V/ns
2. Determined from 1.5V of the rising edge of Data_In to 50% of the rising edge of Data_Out
3. The tD variation between multiple devices measured for same input conditions and same external signal delay
4. Depends on Supply Voltage and Signal Rate
