Centellax
Datasheet
The MC28R36M is a Clock
Recovery Unit (CRU) using
Silicon Germanium (SiGe)
process technology. The module
accepts input data rates at 27.95
Gb/s with an input sensitivity
greater than 50mVppk. The data
input is AC coupled and termi-
nated with a 50 ohm resistor to
minimize reflections. The half-
rate recovered clock is AC-cou-
pled at ECL compatible levels.
The MC28R36M can be used to
extract low jitter clock for 100
GE applications operating at
transmission speeds of 27.95
Gb/s. Broadband test systems
will benefit from the low power
dissipation, precision connectors
and excellent signal quality. The
MC28R36M also locks to half-
rate data to cover 16 Gb/s Fibre
Channel (16 GFC).
27.9 - 36.0 Gb/s Data Rates
High Input Sensitivity
Low Jitter Output Clock
Low Power Consumption
Single -3.3V Power Supply

... For this example, the loop is locked if CKO is 13.975 GHz. 3. Once the loop is locked (i.e. trained), switch the LOCK pin to High, or 0V, to lock onto the data input. *The MC28R36M may also be trained using 1/8 or 1/16 of the data rate as the reference clock input; however, the VCO capture range will be reduced. ...
