Applications
• SONET/SDH and DWDM transport
systems
• Multiservice access platforms and add/
drop multiplexers
• ATM switches and routers
• Digital cross-connect systems
• Optical test equipment
Highlights
• Superior jitter tolerance and transfer jitter
performance
• Low power dissipation
• Single CDR unit for both 155 Mbps and
622 Mbps applications
Microsemi’s newly improved multirate clock and data recovery (CDR)
devices provide exceptional input sensitivity, jitter tolerance, and jitter
transfer performance.
The VSC8115-05 and VSC8115-06 devices derive high-speed timing
signals for SONET/SDH-based equipment. The devices are designed
to operate with SONET framer or ASIC devices to provide a low-power,
high-speed clock and data recovery interface for optical networks.
The devices achieve impressive jitter tolerance of 0.45 UI, jitter input
sensitivity of 150 mV, and jitter transfer compliance in JMODE. Meets all
Telcordia, ANSI, ITU-T, and SONET jitter requirements.
The VSC8115-05 and VSC8115-06 feature signal and lock-detect
status outputs, automatic lock-to-reference, and PLL bypass for on-
board debugging. High-speed outputs are confi gurable for either
LVPECL or LVDS.
Available in a 20-pin TSSOP package for fl exible implementation
and simplifi ed layout, the VSC8115-05 device supports commercial
temperature ranges, and the VSC8115-06 supports industrial
temperature ranges. Both devices come in tape and reel form and are
available in lead(Pb)-free versions.
