Functional Description The ZL30414 ZL30414 is an analog phased-locked loop which provides rate conversion and jitter attenuation for SONET/SDH OC-192/STM-64 OC-192/STM-64, OC-48/STM-16 OC-48/STM-16, OC-12/STM-4 OC-12/STM-4 and OC-3/STM-1 applications. A functional block diagram of the ZL30414 ZL30414 is shown in Figure 1 and a brief description is presented in the following sections. 1.1 Frequency/Phase Detector The Frequency/Phase Detector compares the frequency/phase of the input reference signal with the feedback signal from the Frequency Divider circuit and provides an error signal corresponding to the frequency/phase difference between the two. This error signal is passed to the Loop Filter circuit. 1.2 Lock Indicator The ZL30414 ZL30414 has a built-in LOCK detector that measures frequency difference between input reference clock C19i and the VCO frequency. When the VCO frequency is less than ±300 ppm apart from the input reference frequency then the LOCK pin is set high. The LOCK pin is pulled low if the frequency difference exceeds ±1000 ppm. 1.3 Loop Filter The Loop Filter is a low pass filter. This low pass filter ensures that the network jitter requirements are met for an input reference frequency of 19.44 MHz. The corner frequency of the Loop Filter is configurable with an external capacitor and resistor connected to the LPF pin and ground as shown in Figure 3.

ZL30414 ZL30414 1.4 Data Sheet VCO The voltage-controlled oscillator (VCO) receives the filtered error signal from the Loop Filter, and based on the voltage of the error signal generates a primary frequency. The VCO output is connected to the "Frequency Dividers and Clock Drivers" block that divides VCO frequency and buffer generated clocks. 1.5 Output Interface Circuit The output of the VCO is used by the Output Interface Circuit to provide four LVPECL differential clocks at 622.08 MHz, one CML differential clock at 155.52 MHz and a single-ended 19.44 MHz output clock. This block provides also a 19.44MHz feedback clock that closes PLL loop. Each output clock can be enabled or disabled individually with the associated Output Enable pin.

If any of the LVPECL outputs are disabled they must be left open without any terminations. 6 Zarlink Semiconductor Inc. ZL30414 ZL30414 2.0 Data Sheet ZL30414 ZL30414 Performance The following are some of the ZL30414 ZL30414 performance indicators that complement results listed in the Characteristics section of this data sheet. 2.1 Input Jitter Tolerance Jitter tolerance is a measure of the PLL's ability to operate properly (i.e., remain in lock and/or regain lock in the presence of large jitter magnitudes at various jitter frequencies) when jitter is applied to its input reference. The input jitter tolerance of the ZL30414 ZL30414 is shown in Figure 4. On this graph, the single line at the top represents measured input jitter tolerance and the three overlapping lines below represent minimum input jitter tolerance for OC-192 OC-192, OC-48 OC-48, and OC-12 OC-12 network interfaces. The jitter tolerance is expressed in picoseconds (pk-pk) to accommodate requirements for interfaces operating at different rates. Figure 4 - Input Jitter Tolerance 7 Zarlink Semiconductor Inc. ZL30414 ZL30414 2.2 Data Sheet Jitter Transfer Characteristic Jitter Transfer Characteristic represents a ratio of the jitter at the output of a PLL to the jitter applied to the input of a PLL. This ratio is expressed in dB and it characterizes the PLLs ability to attenuate (filter) jitter. The jitter transfer characteristic for the ZL30414 ZL30414 configured with recommended loop filter components (RF=8.2 k, CF=470 nF) is shown in Figure 5. The plotted curves represent jitter transfer characteristics over the recommended voltage (3.0V to 3.6V) and temperature (-40C to 85C) ranges.
