ZL30109
DS1/E1 System Synchronizer with 19.44 MHz Output
Overview
| The ZL30109 DS1/E1 System Synchronizer contains a digital phase-locked loop (DPLL), which provides timing and synchronization for multi-trunk DS1 and E1 transmission equipment. The 19.44 MHz output makes the ZL30109 also suitable for SDH line card applications. |
Typical Applications
- Synchronization and timing control for DSLAM, Gateway and PBX systems that require Stratum 4/4E timing
- Line Card synchronization for SDH/PDH applications
- Clock and frame pulse source for ST-BUS, GCI and other time division multiplex (TDM) buses
Features & Benefits
- Supports Telcordia GR-1244-CORE Stratum 4 and Stratum 4E
- Supports ITU-T G.823 and G.824 for 2048 kbit/s and 1544 kbit/s interfaces
- Supports ANSI T1.403 and ETSI ETS 300 011 for ISDN primary rate interfaces
- Simple hardware control interface
- Accepts two input references and synchronizes to any combination of 2 kHz, 8 kHz, 1.544 MHz, 2.048 MHz, 8.192 MHz, 16.384 MHz or 19.44 MHz inputs
- Provides a range of clock outputs: 1.544 MHz, 2.048 MHz, 16.384 MHz, 19.44 MHz and either 4.096 MHz and 8.192 MHz or 32.768 MHz and 65.536 MHz
- Provides 5 styles of 8 kHz framing pulses and a 2 kHz multi-frame pulse
- Holdover frequency accuracy of 1.5 x 10-7
- Lock, Holdover and selectable Out of Range indication
- Selectable loop filter bandwidth of 1.8 Hz or 922 Hz
- Less than 24 psrms intrinsic jitter on the 19.44 MHz output clock, compliant with OC-3 and STM-1 jitter specifications
- Less than 0.6 nspp intrinsic jitter on all output clocks
- External master clock source: clock oscillator or crystal
