SYNCHRONOUS EQUIPMENT
CLOCK/SYNCHRONIZER - SY02-PLL2
Date: December 12, 2003
• INTRODUCTION
The SY02-PLL2 is a crystal-based PLL synchronizer designed as a module level subsystem for easy incorporation
into telecommunication equipment.
• FEATURES
- Low jitter output from intrinsically low jitter VCXO;
- Two references inputs, user selects the frequencies;
- Alarms and status;
- Buffered reference output;
- Tri-state (high impedance) reference and oscillators outputs;
- Provides free running clock output of ±20ppm;
- The unit changes timing modes in response to external events;
- J-TAG service port for re-programming and servicing;
• APPLICATIONS
- Line Cards
- ATM
- SDH
- PDH
- SONET
- Other telecommunication equipment.
