Whatever the operating mode is, the DPLL gives a stable performance without being affected by operating conditions or silicon process variations. The 82V3399 is an integrated, single-chip solution for the Synchronous Equipment Timing Source for Stratum 3, 4E, 4, SMC, EECOption1, EEC-Option2 clocks in SONET / SDH / Synchronous Ethernet equipment, DWDM and Wireless base station. There are 2 high performance APLLs that can be used for low jitter SONET and Ethernet Clocks The device supports several types of input clock sources: recovered clock from Synchronous Ethernet, STM-N or OC-n, PDH network synchronization timing and external synchronization reference timing. The device provides programmable DPLL bandwidths: 0.5 mHz to 560 Hz in 19 steps and damping factors: 1.2 to 20 in 5 steps. Different settings cover all SONET / SDH clock synchronization requirements. The device consists of T0 and T4 paths. The T0 path is a high quality and highly configurable path to provide system clock for node timing synchronization within a SONET / SDH / Synchronous Ethernet network. The T4 path is simpler and less configurable for equipment synchronization. The T4 path locks independently from the T0 path or locks to the T0 path. A highly stable input is required for the master clock in different applications. The master clock is used as a reference clock for all the internal circuits in the device. It can be calibrated within ±741 ppm. All the read/write registers are accessed through a microprocessor interface. The device supports I2C and serial microprocessor interface modes. An input clock is automatically or manually selected for T0 and T4 path. Both the T0 and T4 paths support three primary operating modes: Free-Run, Locked and Holdover. In Free-Run mode, the DPLL refers to the master clock. In Locked mode, the DPLL locks to the selected input clock. In Holdover mode, the DPLL resorts to the frequency data SYNCHRONIZATION MANAGEMENT WAN PLL AND CLOCK GENERATIION FOR IEEE-1588 In general, the device can be used in Master/Slave application. In this application, two devices should be used together to enable system protection against single chip failure. 10 REVISION 9 01/05/16 82V3399 SHORT FORM DATA SHEET FUNCTIONAL BLOCK DIAGRAM T4 Input Selector T4 APLL MUX T4 DPLL T4 APLL OUT1 MUX Divider OUT1 OUT2 MUX Divider OUT2 OUT3 MUX Divider OUT3 OUT4 MUX Divider OUT4 OUT5 MUX Divider OUT5_POS OUT5_NEG OUT6 MUX Divider OUT6_POS OUT6_NEG Auto Divider FRSYNC_8K_1PPS Auto Divider MFRSYNC_2K_1PPS Input IN1 IN2 Input Pre-Divider Priority Input Pre-Divider Priority IN3 IN4 IN5 IN6 Input Pre-Divider Priority Input Pre-Divider Priority Input Pre-Divider Priority Input Pre-Divider Priority EX_SYNC1 EX_SYNC2 Monitors Selection T0 Input Selector T0 APLL MUX T0 DPLL T0 APLL Microprocessor Interface APLL JTAG OSCI Output Figure 1.
