Replacement verdict
Compatible functional replacement candidate
The AD9513BCPZ and AD9511BCPZ are both clock distribution ICs from the same Analog Devices AD951x family, sharing a common 48-lead LFCSP footprint and 3.3 V core supply, so the AD9513BCPZ can serve as a functional replacement candidate for the AD9511BCPZ in many designs. However, the two devices differ in output configuration and channel count, so the replacement is not a drop-in equivalent and requires validation of the output interface, channel requirements, and timing specifications against the target application before adoption.

Key electrical and mechanical differences between the two devices
| Parameter | AD9513BCPZ | AD9511BCPZ | Why it matters |
|---|---|---|---|
| Number of Outputs | 3 outputs (2 LVPECL, 1 LVDS/CMOS) | 5 outputs (4 LVPECL, 1 LVDS/CMOS) | Output count determines how many clock destinations can be driven, directly affecting fan-out capability and board architecture. |
| Input Frequency Range | Up to 1.6 GHz | Up to 1.6 GHz | Maximum input frequency defines the highest reference clock the device can accept before internal division. |
| Output Frequency Range | Up to 1.6 GHz (LVPECL) | Up to 1.6 GHz (LVPECL) | Output frequency ceiling constrains the clock rates deliverable to downstream converters and logic. |
| On-Chip VCO | No | No | Absence of an internal VCO means an external clock source is required, affecting BOM and loop filter design. |
| Divider Range | 1 to 32 (programmable) | 1 to 32 (programmable) | Programmable dividers allow flexible generation of multiple related clock frequencies from one source. |
| Output Logic Types | LVPECL, LVDS, CMOS | LVPECL, LVDS, CMOS | Supported logic standards determine compatibility with downstream receiver interfaces. |
| Additive Jitter | ~0.2 ps RMS (typical) | ~0.2 ps RMS (typical) | Low additive jitter is critical for maintaining signal integrity in high-speed data converters and serial links. |
| Supply Voltage | 3.3 V | 3.3 V | Supply voltage must match the board power rail; mismatches require level shifting or redesign. |
| Package | 32-lead LFCSP | 48-lead LFCSP | Package footprint and pin count affect PCB layout and are not drop-in interchangeable between the two parts. |
| Control Interface | SPI (3-wire) | SPI (3-wire) | Serial control interface compatibility ensures the same host firmware can configure either device. |

Frequently asked questions
What are the key differences between the AD9513BCPZ and AD9511BCPZ?
The AD9513BCPZ is a 3-output clock distribution IC with integrated dividers and delay adjustment, while the AD9511BCPZ is a 5-output clock distribution IC with integrated dividers, delay adjustment, and an on-chip VCO divider. The AD9511BCPZ offers more outputs and additional signal routing flexibility compared to the AD9513BCPZ.
Are the AD9513BCPZ and AD9511BCPZ pin-compatible?
No. The AD9513BCPZ and AD9511BCPZ are not pin-compatible. They have different pin counts and pin functions, so a direct drop-in replacement on the same PCB layout is not possible without design changes.
What package do the AD9513BCPZ and AD9511BCPZ use?
Both the AD9513BCPZ and AD9511BCPZ are offered in a 32-lead LFCSP (lead frame chip scale package) with an exposed pad. The "BCPZ" suffix indicates the RoHS-compliant LFCSP package option from Analog Devices.
How many clock outputs does each device provide?
The AD9513BCPZ provides 3 clock outputs, while the AD9511BCPZ provides 5 clock outputs. The additional outputs on the AD9511BCPZ make it suitable for systems requiring more clock fan-out.
Do both devices support adjustable delay on their outputs?
Yes. Both the AD9513BCPZ and AD9511BCPZ include programmable delay adjustment on their outputs, allowing fine timing alignment between clock channels. The delay settings are configured through the device's serial interface.
What is the maximum output frequency of the AD9513BCPZ and AD9511BCPZ?
Both devices support clock output frequencies up to 1.6 GHz on their LVPECL outputs, based on the Analog Devices datasheet specifications. Actual achievable frequency depends on the input clock source and divider configuration.
Can the AD9511BCPZ replace the AD9513BCPZ in an existing design?
Not directly. Although both are clock distribution ICs from the same family, the AD9511BCPZ has a different pinout, a different number of outputs, and additional internal blocks. A replacement requires PCB redesign and revalidation against the system clock requirements.
