ZL301672-Ch Line Card Network Synchronizer | Integrated Circuits (ICs) | 1 | Active | The ZL30167 is a dual channel Clock Translator combining two programmable DPLLs / NCOs with four programmable synthesizers to support any communication service over optical networks. For applications that require synchronizing to a 1PPS input, the ZL30167 supports a sync pulse/clock pair feature. Any of the inputs can be used for a 1PPS signal shared with any other input for a reference frequency. The output will be synchronized to the input reference and will be phase aligned to the 1PPS input. This unique feature allows a line card with a crystal to be used for synchronizing to a 1PPS input. This normally requires a PLL with a 30mHz bandwidth and TCXO. With very low power consumption, the ZL30167 operates from a single crystal resonator or clock oscillator. It is capable of accepting any frequency from 1kHz to 750MHz on up to eleven input references and generating any frequency from 1Hz to 750MHz on up to sixteen output clocks. |
ZL301684-Ch Line Card Network Synchronizer | Clock/Timing | 1 | Active | The ZL30168 is a Quad Channel Enhanced Clock Translator. Four independent channels can function as DPLLs, NCO's or OTN clock generators based on buffer-fill levels. It can accept any frequency from 1kHz to 750MHz and generate any frequency from 1Hz to 750MHz to support any communication service over optical networks. The ZL30168 operates from a single crystal resonator or clock oscillator supporting eight input references configurable as single ended or differential. It supports eight high performance LVPECL outputs and eight high performance LVCMOS outputs. |
ZL301691-Ch Low Cost OTN Jitter Attenuator | Clock/Timing | 1 | Active | [CREATE AND SAMPLE YOUR CUSTOM ZL30169 HERE](https://clockworks.microchip.com/microchip/design/inputZL)
The ZL30169 is a high performance OTN clock translator that provides output clocks with jitter performance of 250fs RMS. The device integrates a digital phase locked loop (DPLL), analog PLL and EEPROM into a tiny 5x5mm 32 pin QFN package. With programmable loop bandwidth from 14Hz to 500 Hz the DPLL provides hitless reference switching, holdover and jitter filtering. The integrated APLL generates the ultra-low jitter output clocks programmable to any frequency from <1Hz to 1035MHz. The integrated EEPROM provides automatic self-configuration of the device at start-up. |
ZL301744-Ch Line Card OTN Network Synchronizer | Application Specific Clock/Timing | 1 | Active | [ZL30644A](https://www.microchip.com/en-us/product/zl30644a) is recommended as the replacement for new designs.
The ZL30174 features four independent flexible rate conversion clock channels via four digital PLLs and four clock generators. Each channel accepts and generates any frequency from 1 Hz to 900 MHz to support any communication service over optical networks. The ZL30174 operates from a single crystal resonator or clock oscillator supporting up to ten input references configurable as single ended or differential. It generates up to 12 high performance outputs.
