ZL30119GGG

Overview

The ZL30119GGG is a SONET/SDH telecommunications integrated circuit manufactured by Microchip Technology. It functions as a line card synchronizer capable of synthesizing protected telecom line interface clocks compliant with Telcordia GR-253-CORE and ITU-T G.813 standards. The device features an internal Analog Phase-Locked Loop (APLL) to synchronize with standard telecom system references. It operates within a supply voltage range of 2.97V to 3.63V and supports a maximum frequency of 622.08MHz. The component utilizes LVCMOS input and provides LVCMOS or LVPECL outputs, housed in a 100-CABGA (9x9) package.

Procurement Notes

Verify the current status of the ZL30119GGG, as distributor records indicate it may be discontinued. Confirm compatibility with existing design requirements regarding the 100-CABGA package and electrical specifications before procurement planning. Check for official Product Change Notifications from Microchip Technology regarding manufacturing updates or end-of-life notices.

Selection Notes

Select the ZL30119GGG for applications requiring strict compliance with Telcordia GR-253-CORE and ITU-T G.813 standards for SONET/SDH networks. Ensure the design accommodates the 2.97V to 3.63V supply voltage range and the specific LVCMOS/LVPECL output configurations. Verify that the 100-CABGA footprint fits the target PCB layout constraints.

Part Context

The ZL30119 belongs to the ZL301xx family of SONET/SDH support circuits originally developed by Zarlink Semiconductor, which was later acquired by Microsemi and subsequently Microchip Technology. This series includes variants such as the ZL30117 and ZL30121, designed for various line card synchronization needs in optical transport networks.

Replacement Considerations

Publicly available substitute part numbers are not confirmed in the provided documentation. Evaluate other members of the ZL301xx family, such as the ZL30121GGGV2, for potential functional equivalence, subject to verification of pinout and specification compatibility.
