CA1249 Integrated Half-Rate
Clock Driver and Phase Shifter
WJ’s 10Gbps clock amplifier
An RF evolution for OC-192
The CA1249 is another addition in WJ’s series of
hybrid-based products optimized for OC-192 networks.
The CA1249 is a full-function clock driver for generating transmit pulses in optical RZ systems operating
with clock rates between 10.7 and 12.5 GHz (up to
12.5 Gbps FEC data rates). The CA1249 amplifies
clock signals while providing analog phase shift control. Excellent phase shift accuracy, low phase variation over temperature and stable output level performance work in conjunction with the integral power
• 10.7 to 12.5 Gbps Clock Rates
Tunable 200MHz about any Fo
detector to ensure precise control of transmitted pulses.
• 360˚Analog Phase Shift Range
• 16 Vp-p Output Voltage
• Fully Qualified
levels with low power consumption. Custom perform-
The CA1249’s efficiency enables high output voltage
ance and functionality are available
