Replacement verdict
Compatible functional replacement candidate
The AD9514BCPZ and AD9513BCPZ are functionally related clock distribution ICs from the same Analog Devices AD951x family, sharing a common 32-lead LFCSP footprint and core clock fanout architecture. However, they are not identical drop-in substitutes: the AD9514BCPZ integrates an on-chip VCO with a wider output frequency range and adjustable delay, while the AD9513BCPZ provides a fixed divide-by-1/2/4 fanout without an integrated VCO. Designers should validate output configuration, frequency planning, and reference clock requirements before substituting one for the other in an existing design.

Frequently asked questions
What are the key differences between the AD9514BCPZ and AD9513BCPZ?
The AD9514BCPZ is a 1.6 GHz clock distribution IC with two LVPECL outputs and one LVDS output, plus an integrated integer divider (divide-by-1 to 32). The AD9513BCPZ is a 800 MHz clock distribution IC with three LVDS outputs and an integer divider (divide-by-1 to 32). The AD9514 offers higher output frequency and includes LVPECL outputs, while the AD9513 provides three LVDS outputs at a lower maximum frequency.
Are the AD9514BCPZ and AD9513BCPZ pin-compatible?
Both devices are offered in the same 32-lead LFCSP (5 mm × 5 mm) package, but they are not functionally pin-compatible because the output driver types and channel configurations differ. The AD9514 has two LVPECL and one LVDS output, whereas the AD9513 has three LVDS outputs. PCB layout and output termination must be designed for the specific device.
What is the maximum output frequency of each device?
The AD9514BCPZ supports output frequencies up to 1.6 GHz. The AD9513BCPZ supports output frequencies up to 800 MHz. The applicable limit depends on the output driver type and the configured divider ratio.
What output logic types does each device provide?
The AD9514BCPZ provides two LVPECL outputs and one LVDS output. The AD9513BCPZ provides three LVDS outputs. Output termination and PCB routing should follow the respective datasheet recommendations for each logic family.
Do both devices include an integer divider?
Yes. Both the AD9514BCPZ and AD9513BCPZ include an integer divider with divide ratios from 1 to 32. The divider setting is programmed through the device's serial interface and affects the output frequency relative to the input clock.
What is the difference in additive jitter between the AD9514BCPZ and AD9513BCPZ?
Both devices are specified with low additive jitter suitable for clock distribution. The exact additive jitter specification depends on the output type, frequency, and measurement conditions, and should be taken from the respective manufacturer datasheet rather than assumed to be identical between the two parts.
Can the AD9513BCPZ be used as a drop-in replacement for the AD9514BCPZ?
No. Although both are 32-lead LFCSP devices, the output driver types differ (three LVDS versus two LVPECL plus one LVDS), and the maximum output frequency differs (800 MHz versus 1.6 GHz). A replacement requires validating output logic compatibility, termination, frequency requirements, and register configuration against the target design.
What supply voltage do the AD9514BCPZ and AD9513BCPZ require?
Both devices operate from a 3.3 V supply. Designers should confirm the exact supply range and current consumption from the manufacturer datasheet for the specific operating conditions and output configuration used in the application.
