AD9540BCPZ

AD9540BCPZ Description

The AD9540BCPZ from Analog Devices Inc. is a high-performance clock generator designed for precision timing applications. Housed in a compact 48-lead LFCSP package, it operates within a 1.71V to 1.89V supply range and supports clock input frequencies up to 655MHz. This device integrates a PLL (Phase-Locked Loop) for stable clock synthesis, offering 2:2 input-to-output ratio with differential signaling (CML/PECL) for robust noise immunity. Its divider/multiplier functionality (divider-only) enables flexible frequency scaling, making it ideal for systems requiring precise clock distribution. The AD9540BCPZ is RoHS3 compliant and rated for MSL 3 (168 hours), ensuring reliability in industrial and commercial environments.
