Microchip Technology, Inc. Clock and Timing IC ZL30132GGG2

The ZL30132GGG2 from Quarktwin Technology Ltd. is an application-specific clock/timing device designed for synchronization in telecom and Ethernet applications. It supports standard telecom reference clocks and Ethernet reference clocks, providing jitter-filtered output clocks suitable for SONET/SDH, PDH, and Ethernet network interface cards. The device complies with ITU-T G.8262 standards for synchronous Ethernet Equipment slave Clocks. This product features automatic hitless reference switching and short-term holdover capabilities during loss of reference inputs. It generates standard SONET/SDH clock rates and Ethernet clock rates, with a programmable synthesizer that can produce clock frequencies in multiples of 8 kHz up to 100 MHz. The ZL30132GGG2 also allows for configurable input to output delay and output to output phase alignment, and it can be controlled via a serial interface (SPI or I¬=C). The device is suitable for applications including ITU-T G.8262 line cards supporting 1GbE and 10GbE interfaces, as well as SONET line cards up to OC-192 and SDH line cards up to STM-64. It operates within a temperature range of -40¬8C to +85¬8C and is packaged in a 64-pin CABGA format.
