The ZL80001QAB1 is a T1/E1 system synchronizer manufactured by Microchip Technology. It functions as a telecom interface IC designed for clock synchronization in telecommunications networks. The device supports lead-free specifications and complies with RoHS standards. It is classified under the telecom interface category, providing essential timing signals for T1 and E1 protocols.
This component is officially listed as obsolete or discontinued by the manufacturer. Availability is restricted, and current stock levels are limited or non-existent through standard distribution channels. Verify end-of-life status and obsolescence notices directly with authorized suppliers before procurement planning.
Due to the obsolete status of this part, direct replacement is not feasible without design modification. Engineers should evaluate alternative components that offer compatible T1/E1 synchronization capabilities and interface requirements to ensure system continuity.
The ZL80001QAB1 belongs to Microchip's legacy portfolio of telecom interface solutions. It was designed to address specific timing needs in traditional T1 and E1 infrastructure, serving as a critical component for maintaining signal integrity in older telecommunications architectures.
Microchip recommends the ZL30151LDG1 as a public substitute for the ZL80001QAB1. Both parts share RoHS3 and REACH compliance, MSL3 classification, and telecom interface compatibility.
