Functional Description The ZL30119 SONET/SDH Line Card Synchronizer is a highly integrated device that provides timing and synchronization for network interface cards. It incorporates two independent DPLLs, each capable of locking to one of eight input references and provides ...
Page 13
DPLL Mode Control Both DPLL1 and DPLL2 independently support three modes of operation - free-run, normal and holdover. The mode of operation can be manually set or controlled by an automatic state machine as shown in Figure 2. Reset ...
Page 14
Ref and Sync Inputs There are eight reference clock inputs (ref0 to ref7) available to both DPLL1 and DPLL2. The selected reference input is used to synchronize the output clocks. Each of the DPLLs have independent reference selectors which ...
Page 15
Each of the ref inputs accept a single-ended LVCMOS clock with a frequency ranging from 2 kHz to 77.76 MHz. Built-in frequency detection circuitry automatically determines the frequency of the reference if its frequency is within the set of pre-defined ...
Page 16
Coarse Frequency Monitor (CFM) The CFM block monitors the reference frequency over a measurement period of 30 µs so that it can quickly detect large changes in frequency. A CFM failure (cfm_fail) is triggered when the frequency has changed by ...
Page 17
The feedback clock (fb_clk) of DPLL1 is available as an output clock. Its output frequency is always equal to DPLL1’s selected input frequency. The output clocks and frame pulses derived from the SONET/SDH APLL are always synchronous with DPLL1, and ...
Page 18
Configurable Input-to-Output and Output-to-Output Delays The ZL30119 allows programmable static delay compensation for controlling input-to-output and output-to-output delays of its clocks and frame pulses. All of the output synthesizers (SONET/SDH, P0, P1, Feedback) locked to DPLL1 can be configured ...
Page 19
Software Configuration The ZL30119 is mainly controlled by accessing software registers through the serial peripheral interface (SPI). The device can be configured to operate in a highly automated manner which minimizes its interaction with the system’s processor ...
