data lanes, where each half-duplex lane consists of a differential equal-
izer, as well as a transmit driver that includes de-emphasis.
medium between various platforms and ICs in all types of computing
environments: computing, storage, consumer electronics, and communi-
cation applications. The 89HP0502U is targeted to meet the high-perfor-
mance needs of USB 3.0 applications.

Device Description
block that supports a 100 ohm termination for normal operation. It also
supports a high-impedance (Hi-Z) mode, whereby the receive termina-
tions are placed into a Hi-Z mode.
receiver over 60 inches of FR4 @ 5Gbps while the wide-swing transmit
drive offers up to 8.5dB of transmit de-emphasis.
indicates when the envelope has fallen below a programmable
threshold. When electrical idle is detected on the receiver, the signal
detect output is used to place the transmitter into electrical idle.
tion block that supports a 100 ohm termination for normal operation. It
will also support the following additional terminations:
provides 0 to 8.5dB of transmit equalization and supports Squelch Mode
where the outputs go to common-mode with an exit/entry latency of less
than 8ns. Both the amplitude and equalization are programmable.
Receiver Variable Termination: Is a ground referenced termination
Equalizer: Provides up to 30dB equalization capability in the
Signal Detect: Measures the envelope of the incoming signal and
Transmitter Variable Termination: Is a supply referenced termina-
Output Driver: Provides 400 - 800 mVdiff-pkpk output swing. It also
– Squelch mode: The transmitter supports a Squelch mode,
– Standby mode: The transmit terminations are increased to
whereby the transmitter stops toggling and maintains the
transmit common-mode voltage.
