Replacement verdict
Compatible functional replacement candidate
The ADN2915ACPZ and ADN2913ACPZ-RL7 are both single-channel clock and data recovery ICs from the same Analog Devices ADN291x family, sharing a common LFCSP package and 2.5 V to 3.3 V supply range, so the ADN2913ACPZ-RL7 is a viable functional replacement candidate for the ADN2915ACPZ in many designs. However, the two parts differ in their supported data rate range and jitter performance specifications, so the target data rate and jitter budget must be validated against the ADN2913ACPZ-RL7 datasheet before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | ADN2915ACPZ | ADN2913ACPZ-RL7 | 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 equalizer for compensating signal degradation over long traces or cables, while the ADN2913 does not, affecting link budget and reach. |
| Data Rate Range | Up to 11.3 Gbps | Up to 11.3 Gbps | Both support similar high-speed serial data rates, making them candidates for comparable optical module and backplane applications. |
| Integrated Equalizer | Yes | No | An integrated equalizer extends reach and improves jitter performance over lossy media; its absence in the ADN2913 limits use to shorter or cleaner channels. |
| Jitter Tolerance | Enhanced with equalization | Standard CDR jitter tolerance | Better jitter tolerance improves bit error rate margins in noisy or degraded links, which is critical for reliable high-speed communication. |
| Package | 32-lead LFCSP | 32-lead LFCSP | Identical package and footprint allow potential drop-in replacement on the same PCB layout. |
| Supply Voltage | 1.8 V core / 2.5 V or 3.3 V I/O (typical) | 1.8 V core / 2.5 V or 3.3 V I/O (typical) | Matching supply requirements simplifies power design and ensures compatibility with existing board power rails. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Industrial temperature range supports use in telecom and datacom equipment exposed to harsh environments. |
| Application Focus | Long-reach optical modules and lossy backplanes | Short-reach optical modules and clean backplanes | The equalizer in the ADN2915 targets extended reach, while the ADN2913 suits cost-sensitive short-reach designs, affecting substitutability by link length. |

Frequently asked questions
What are the ADN2915ACPZ and ADN2913ACPZ-RL7?
Both are Analog Devices clock and data recovery (CDR) ICs for optical and high-speed serial applications. The ADN2915ACPZ is supplied in a 32-lead LFCSP package, while the ADN2913ACPZ-RL7 is supplied in a 32-lead LFCSP package in tape-and-reel form (RL7 suffix). Both operate from a single supply and support continuous data-rate operation over a specified range.
What is the difference between the ADN2915ACPZ and ADN2913ACPZ-RL7?
The primary difference is the ordering/packaging format: the ADN2915ACPZ is a standard tray/individual package option, while the ADN2913ACPZ-RL7 is the tape-and-reel (RL7) variant intended for automated assembly. The base silicon function (CDR) is the same family; designers should confirm the exact data-rate range and configuration options in the respective datasheets before substitution.
Are the ADN2915ACPZ and ADN2913ACPZ-RL7 pin-compatible?
Both devices are offered in a 32-lead LFCSP package, and the ADN2913 is the tape-and-reel ordering variant of the same package family. Pin compatibility should be verified against the specific datasheet pin configuration for each part number, since pin functions and configuration pins must match for a drop-in replacement.
What data rates do these CDR devices support?
The ADN2915 and ADN2913 are continuous-rate CDRs designed for high-speed serial links. The exact supported data-rate range is specified in the Analog Devices datasheet for each part; designers must confirm the range for the specific part number and operating conditions before use.
What is the purpose of the RL7 suffix on the ADN2913ACPZ-RL7?
The RL7 suffix denotes tape-and-reel packaging (reel of 7-inch format) for automated pick-and-place assembly. It does not change the electrical function of the device; it only defines the shipping/packaging format.
Can the ADN2913ACPZ-RL7 be used as a direct replacement for the ADN2915ACPZ?
Because the ADN2913ACPZ-RL7 is the tape-and-reel ordering variant of the same CDR family in the same 32-lead LFCSP package, it can generally serve as a replacement provided the datasheet-confirmed data-rate range, configuration pin settings, and supply requirements match the target design. Always validate against the manufacturer datasheet before substitution.
What supply voltage do these devices require?
Both devices operate from a single low-voltage supply as specified in the Analog Devices datasheet. The exact nominal supply voltage and tolerance must be confirmed from the official datasheet for the specific part number before designing the power rail.
Are these parts RoHS compliant?
Analog Devices LFCSP-packaged CDR devices in the ADN291x family are generally RoHS-compliant; the exact compliance status and lead-finish details should be confirmed from the manufacturer's product page or datasheet for the specific ordering code (ADN2915ACPZ or ADN2913ACPZ-RL7).
