Functional Description The ZL30415 is an analog phased-locked loop which provides rate conversion and jitter attenuation for SONET/SDH OC-12/STM-4 and OC-3/STM-1 applications. A functional block diagram of the ZL30415 is shown in Figure 1 and a brief description is presented in the following sections. 2.1 Reference Selection Multiplexer The ZL30415 accepts two types of input reference clocks: - differential: operating at 19.44 MHz or 77.76 MHz, compatible with LVDS/LVPECL/CML threshold levels - single-ended: operating at 19.44 MHz, compatible with CMOS switching levels. The REF_SEL input determines whether the single-ended CMOS reference input (REFin) or the differential reference inputs (REFinP/N) are used as input reference clocks. The REF_FREQ input selects the rate of the differential input clock to be either 19.44 MHz, or 77.76 MHz. See Table 1 for details. REF_SEL REF_FREQ Selected Input Reference Reference Frequency 0 x C19i 19.44 MHz (CMOS) 1 0 REFin 77.76 MHz (Differential) 1 1 REFin 19.44 MHz (Differential) Table 1 - Input Reference Selection 4 Zarlink Semiconductor Inc. ZL30415 2.2 Data Sheet 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 equal to the frequency/phase difference between the two. This error signal is passed to the Loop Filter circuit. 2.3 Lock Indicator The ZL30415 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 output is set high. The LOCK output is pulled low if the frequency difference exceeds ±1000 ppm. 2.4 Loop Filter The Loop Filter is a low-pass filter. This low-pass filter eliminates high frequency spectral components from a phase error signal produced by the Phase Detector. This ensures low output jitter that meets network jitter requirements. The corner frequency of the Loop Filter is configurable with an external capacitor and resistor connected to the LPF ball and ground as shown in Figure 3. ZL30415 Frequency and Phase Detector LPF Loop Filter RF VCO RF=8.2 kΩ, CF=470 nF CF Figure 3 - Loop Filter Elements 2.5 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. 5 Zarlink Semiconductor Inc. ZL30415 2.6 Data Sheet Frequency Dividers and Clock Drivers The output of the VCO feeds the high frequency clock to the "Frequency Dividers and Clock Drivers" circuit to provide one differential LVPECL compatible clock with selectable frequency and one single-ended 19.44 MHz C19o output clock. The C19o clock can be enabled or disabled with the associated C19oEN Output Enable ball. Internally, this block provides a feedback clock that closes the PLL loop. The frequency of the OC-CLKo differential output clock is selected with FS3, FS2 and FS1 inputs as is shown in the following table. FS3 FS2 FS1 OC-CLKo Frequency 0 0 0 19.44 MHz 0 0 1 38.88 MHz 0 1 0 77.76 MHz 0 1 1 155.52 MHz 1 0 0 622.08 MHz 1 0 1 Reserved 1 1 0 Reserved 1 1 1 Reserved Table 2 - OC-CLKo Clock Frequency Selection 6 Zarlink Semiconductor Inc. ZL30415 3.0 Data Sheet ZL30415 Performance The following are some of the ZL30415 performance indicators that complement results listed in the Characteristics section of this data sheet. 3.1 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) in the presence of jitter applied to its input reference. The input jitter tolerance of the ZL30415 is shown in Figure 4. On this graph, the single line at the top represents the input jitter tolerance and the three overlapping lines below represent the specification for minimum input jitter tolerance for OC-192, OC-48 and 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 3.2 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 PLL’s ability to attenuate (filter) jitter. The ZL30415 jitter transfer characteristic complies with the maximum 0.1 dB jitter gain specified in Telcordia’s GR-253-CORE. 7 Zarlink Semiconductor Inc. ZL30415 Data Sheet 4.0 Applications 4.1 Generation of Low Jitter SONET/SDH Equipment Clocks The functionality and performance of the ZL30415 complements the entire family of the Zarlink’s advanced network synchronization PLL’s. Its jitter filtering characteristics exceed requirements of SONET/SDH optical interfaces operating up to OC-12/STM-4 rates (622 Mbit/s). The ZL30415 in combination with the MT90401 or the ZL30407 (SONET/SDH Network Element PLL’s) provides the core building blocks for high quality equipment clocks suitable for network synchronization (see Figure 5).
