Replacement verdict
Compatible functional replacement candidate
The AD9515BCPZ and AD9513BCPZ are both clock distribution ICs from the same Analog Devices family and share a common 32-lead LFCSP footprint, making them functionally related candidates. However, they differ in output configuration and channel count, so the AD9513BCPZ is not a direct drop-in substitute for the AD9515BCPZ without verifying the system's output driver and channel requirements.

Key electrical and mechanical differences between the two devices
| Parameter | AD9515BCPZ | AD9513BCPZ | Why it matters |
|---|---|---|---|
| Number of Outputs | 2 (LVPECL + LVDS/CMOS) | 3 (LVPECL, LVDS, CMOS) | Output count determines how many clock destinations can be driven from a single device, affecting fan-out capability in a clock tree. |
| Output Logic Types | LVPECL and LVDS/CMOS | LVPECL, LVDS, and CMOS | The available output standards must match the input requirements of downstream receivers for direct compatibility. |
| Maximum Output Frequency | 1.6 GHz (LVPECL) | 1.6 GHz (LVPECL) | Maximum frequency limits the highest clock rate the device can distribute without degrading signal integrity. |
| Input Frequency Range | Up to 1.6 GHz | Up to 1.6 GHz | The input range must accommodate the reference or source clock to ensure proper locking and distribution. |
| Additive Jitter | ~0.2 ps RMS (typical) | ~0.2 ps RMS (typical) | Low additive jitter preserves clock signal quality, critical for high-speed data converters and serial links. |
| Package Type | 32-Lead LFCSP | 32-Lead LFCSP | Package footprint and pinout affect PCB layout and whether the parts are drop-in compatible. |
| Supply Voltage | 3.3 V | 3.3 V | Supply voltage must match the board power rail; mismatches require level shifting or additional regulation. |
| On-Chip Divider | Yes (programmable dividers) | Yes (programmable dividers) | Integrated dividers allow flexible clock scaling without external components, simplifying clock tree design. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | The temperature range must cover the application environment to guarantee reliable operation. |

Frequently asked questions
What are the key differences between the AD9515BCPZ and AD9513BCPZ?
The AD9515BCPZ is a 1.6 GHz clock distribution IC with two LVPECL outputs and two LVDS outputs, while the AD9513BCPZ is a 800 MHz clock distribution IC with three LVPECL outputs and one LVDS output. The AD9515 offers higher maximum output frequency and a different output channel configuration compared to the AD9513.
Are the AD9515BCPZ and AD9513BCPZ pin-compatible?
No. Although both devices are offered in a 32-lead LFCSP package, their pin functions and output configurations differ. The AD9515BCPZ provides two LVPECL and two LVDS outputs, whereas the AD9513BCPZ provides three LVPECL outputs and one LVDS output, so the PCB layout and pin assignments are not interchangeable.
What is the maximum output frequency of each device?
The AD9515BCPZ supports a maximum output frequency of 1.6 GHz, while the AD9513BCPZ supports a maximum output frequency of 800 MHz. The AD9515 is therefore suited to higher-speed clock distribution applications.
What output logic types are available on each device?
The AD9515BCPZ provides two LVPECL outputs and two LVDS outputs. The AD9513BCPZ provides three LVPECL outputs and one LVDS output. Both devices include a programmable divider and delay adjustment features for clock distribution.
Do both devices support the same supply voltage?
Yes. Both the AD9515BCPZ and AD9513BCPZ operate from a 3.3 V supply, consistent with their datasheet specifications. Designers should still verify the exact recommended operating conditions in the respective manufacturer datasheets.
Can the AD9513BCPZ be used as a drop-in replacement for the AD9515BCPZ?
No. Because the two devices differ in maximum output frequency, output channel configuration, and pin functions, the AD9513BCPZ is not a drop-in replacement for the AD9515BCPZ. Any substitution requires validation against the target design requirements and manufacturer documentation.
What package do the AD9515BCPZ and AD9513BCPZ use?
Both the AD9515BCPZ and AD9513BCPZ are supplied in a 32-lead LFCSP (lead frame chip scale package). The package outline is similar, but pin assignments and internal functions differ between the two parts.
