SY02-HP2O
SYNCHRONOUS EQUIPMENT
LOW INPUT/ HIGH DUAL OUTPUT FREQUENCY CLOCK/SYNCHRONIZER
SY02-HP2O
Date: January 20, 2004
• INTRODUCTION
The SY02-HP2O is a high frequency 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 or VCSO;
- One pre-selected input reference of 8kHz to 77.76MHz (CMOS levels);
- Two pairs of high frequency differential LVPECL outputs up to 800MHz. (must be at the same frequency)
- Alarms and status;
- Provides free running clock output;
- The unit changes timing modes in response to external events;
- J-TAG service port for re-programming and servicing;
- 3.3V DC power supply
- Small dimensions: 0.75” x 1.20” SMT pkg.
• APPLICATIONS
- ATM
- SDH
- PDH
- SONET
- Other telecommunication equipment.

• DESCRIPTION
The SY02-HP2O is a High Frequency Phase Lock Loop has been designed as a module level subsystem for easy
incorporation into telecommunication equipment. The module generates the high frequency (up to 622.08MHz)
output from a low jitter VCXO or VCSO (SAW based oscillators). The output can be disabled externally by setting
OUTEN pin high. The SY02-HP2O can be locked to one reference of a pre-selected input frequency between 8 kHz
to 77.76MHz. The module has fast locking time and tolerates reference inputs with different duty cycles. The loop
bandwidth is optimized according to used VCXO and wanted output performance. The SMD package dimensions
are 0.75x1.20 inch and power supply is 3.3V. Parts are assembled using high temperature solder to withstand
surface mount reflow process.
