Typical Applications
Fast Rise and Fall Times: <11ps
The HMC-C062 is ideal for:
Single -3.3V Power Supply
• OC-768 and SDH STM-256 Equipment
Hermetically Sealed Module: 1.85mm connectors
• Serial Data Transmission up to 50 Gbps
-40°C to +70°C Operating Temperature
• Short, intermediate, and long haul
fiber optic applications
General Description
The HMC-C062 is a fanout buffer designed to support
data transmission rates of up to 50 Gbps. The device
can also operate with clock signals up to 30 GHz.
The input is broadband from DC to 30 GHz. During
normal operation, input data (or clock) is transferred to
both output channels. Differential input signals to the
HMC-C062 are terminated with 50 Ohms to ground
on-chip, and may be either AC or DC coupled. The
differential outputs of the HMC-C062 may be either
AC or DC coupled. Outputs can be connected directly
to a 50 Ohm to ground terminated system, while DC
blocking capacitors may be used if the terminating
system is 50 Ohms to a non-ground DC voltage. The
HMC-C062 operates from a single -3.3V DC supply,
and is housed in a hermetically sealed module with
1.85mm connectors.
