HIGH IN/OUTPUT FREQUENCY CLOCK/SYNCHRONIZER - SY02-HIPL
Date: January 6, 2004
• INTRODUCTION
The SY02-HIPL 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 references LVEPECL input up to 800MHz (pre-select frequency value –upon order)
- One high frequency LVPECL output up to 800MHz with E/D function (pre-select frequency value –upon order)
- 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: 0.96” x 1.050”
• APPLICATIONS
- ATM
- SDH
- PDH
- SONET
- Other telecommunication equipment.

• DESCRIPTION
The SY02-HIPL 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 (Crystal Based Oscillator) or VCSO (SAW based oscillators). The output can be
disabled externally by setting OUTEN pin high. The SY02-HIPL can be locked to one reference input frequency of
155.52MHz. 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 ALARM output signals
monitor the status of the phase loop LOL (Loss of Lock) and LOR (Loss of Reference). If the reference REF IN is
absent, the SY02-HIPL will automatically switch to free run mode and FRS output will indicate it. The SMD package
dimensions are 0.96x1.050 inch and power supply is 3.3V.
