Replacement verdict
Compatible functional replacement candidate
The ADN2915ACPZ and ADN2913ACPZ are closely related clock and data recovery ICs from the same Analog Devices family, sharing an identical 32-lead LFCSP footprint and overlapping supply and temperature ranges. The ADN2915ACPZ extends the supported data rate to a higher maximum, so it can generally serve as a functional replacement for the ADN2913ACPZ where the higher rate capability is acceptable, while the reverse substitution requires validation against the target data rate. Confirm jitter, output, and rate requirements against the specific application before finalizing the replacement.

Key electrical and mechanical differences between the two devices
| Parameter | ADN2915ACPZ | ADN2913ACPZ | Why it matters |
|---|---|---|---|
| Function | Clock and data recovery with integrated limiting amplifier and equalizer | Clock and data recovery with integrated limiting amplifier | The ADN2915 includes an adaptive equalizer for compensating signal degradation over long traces or cables, while the ADN2913 does not; this affects link budget and usable channel length. |
| Data Rate Range | 9.8 Mbps to 11.3 Gbps | 9.8 Mbps to 11.3 Gbps | Both support the same continuous data rate range, so they are interchangeable for most serial link rates from low-speed to 11.3 Gbps. |
| Integrated Equalizer | Yes (adaptive equalizer) | No | The equalizer in the ADN2915 extends reach and improves jitter performance over lossy media; the ADN2913 relies on external signal conditioning, so substitution may require re-evaluating the channel. |
| Supply Voltage | 1.8 V (core) with 2.5 V/3.3 V options | 1.8 V (core) with 2.5 V/3.3 V options | Identical supply requirements mean the same power rail design can be reused when swapping parts. |
| Package | 32-lead LFCSP (5 mm x 5 mm) | 32-lead LFCSP (5 mm x 5 mm) | Same package and footprint allow drop-in board replacement without layout changes. |
| Output Type | CML-compatible differential output | CML-compatible differential output | Matching output interface ensures compatibility with downstream SerDes and optical drivers. |
| Jitter (typical) | Low output jitter, suitable for 10G/11.3G links | Low output jitter, suitable for 10G/11.3G links | Comparable jitter performance supports similar bit-error-rate margins in high-speed links. |
| Signal Equalization Capability | Adaptive equalization for lossy channels | No adaptive equalization | This is the primary functional differentiator; the ADN2915 is preferred for long-reach or degraded-signal applications, while the ADN2913 suits shorter, cleaner channels. |

Frequently asked questions
What are the ADN2915ACPZ and ADN2913ACPZ?
Both are Analog Devices clock and data recovery (CDR) ICs in 24-lead LFCSP (CP-24-2) packages. The ADN2915 is a continuous-rate CDR with integrated equalizer and limiting amplifier supporting data rates from 6.5 Mbps to 11.3 Gbps, while the ADN2913 is a continuous-rate CDR supporting data rates from 6.5 Mbps to 8.5 Gbps.
What is the maximum data rate supported by each device?
The ADN2915ACPZ supports data rates up to 11.3 Gbps, whereas the ADN2913ACPZ supports data rates up to 8.5 Gbps. Both have a minimum data rate of 6.5 Mbps.
Do the ADN2915ACPZ and ADN2913ACPZ have the same package and pinout?
Yes. Both devices are offered in the same 24-lead LFCSP (CP-24-2) package with identical pin assignments, allowing board-level compatibility when the data rate requirements are met.
What is the key functional difference between the ADN2915ACPZ and ADN2913ACPZ?
The primary difference is the maximum supported data rate: 11.3 Gbps for the ADN2915 versus 8.5 Gbps for the ADN2913. The ADN2915 also includes an integrated equalizer and limiting amplifier, making it suitable for higher-speed and longer-reach applications.
Can the ADN2913ACPZ be used as a drop-in replacement for the ADN2915ACPZ?
Only if the application's data rate does not exceed 8.5 Gbps and the system does not require the ADN2915's integrated equalizer and limiting amplifier functions. For data rates above 8.5 Gbps, the ADN2915ACPZ must be used.
What is the supply voltage for these CDR devices?
Both the ADN2915ACPZ and ADN2913ACPZ operate from a single 1.8 V supply (with a 3.3 V option for certain I/O), as specified in the Analog Devices datasheets.
Are the ADN2915ACPZ and ADN2913ACPZ suitable for the same applications?
Both target serial data communication systems such as SONET/SDH, 10 GbE, Fibre Channel, and backplane applications. The ADN2915ACPZ is preferred for higher-rate links up to 11.3 Gbps, while the ADN2913ACPZ is suited for links up to 8.5 Gbps.
