GENERAL DESCRIPTION
The HMC7545 is a unidirectional, quad-channel, protocol and
data rate agnostic, asynchronous signal conditioner, designed
for short and intermediate range optical modules, line cards,
and backplane applications operating at up to 14.2 Gbps.
Each channel provides programmable input equalization, LOS
and receiver detection, automatic output squelch,
programmable output swing and output de-emphasis.
Flexible configuration interface: pin strap, 2-wire interface,
or EEPROM
All high speed differential inputs and outputs of the HMC7545
are current mode logic (CML), terminated on-chip with 50 Ω to
APPLICATIONS
the positive supply, and can be dc-coupled or ac-coupled.
QSFP+ direct attach active copper modules
10 Gb, 40 Gb Ethernet and OTN line cards
The device uses a single supply, 2.5 V or 3.5 V, and its typical
power dissipation is less than 80 mW per channel.
10 Gb, 40 Gb backplane drivers
The HMC7545 is packaged in a 36-lead, 4 mm × 7 mm LFCSP
8 Gb, 16 Gb Fibre Channel and InfiniBand® EDR line cards
and backplane drivers
package and operates from −40°C to +85°C.
