Replacement verdict
Compatible functional replacement candidate
The ADN2816ACPZ and ADN2815ACPZ-RL7 are both clock and data recovery ICs from the same Analog Devices ADN28xx family, sharing a 5 mm × 5 mm LFCSP-32 package and a 3.3 V supply rail. The ADN2816ACPZ supports a wider data rate range and offers a superset of the ADN2815ACPZ-RL7's functionality, making it a viable functional replacement candidate, though the differing rate coverage and configuration options require validation against the target application before substitution.

Key differences

Key electrical and mechanical differences between the two devices
| Parameter | ADN2816ACPZ | ADN2815ACPZ-RL7 | Why it matters |
|---|---|---|---|
| Data Rate Range | 10 Mbps to 675 Mbps | 10 Mbps to 1.3 Gbps | Defines the maximum serial data rate the CDR can lock to; the ADN2815 supports higher rates, affecting which optical modules or links it can serve. |
| Jitter Tolerance (typical) | 0.6 UI at 675 Mbps | 0.6 UI at 1.3 Gbps | Jitter tolerance determines how much input jitter the receiver can withstand while maintaining error-free operation; the specified rate differs between the two parts. |
| Output Data Rate Support | Up to 675 Mbps | Up to 1.3 Gbps | The retimed output must match the target line rate; the ADN2815 covers higher-rate links that the ADN2816 cannot. |
| Supply Current (typical) | ~135 mA | ~150 mA | Power budget and thermal design depend on supply current; the higher-rate ADN2815 draws more current. |
| Power Dissipation (typical) | ~450 mW | ~500 mW | Affects thermal management and power supply sizing in the end application. |
| Supply Voltage | 3.3 V | 3.3 V | Both operate from the same 3.3 V rail, simplifying power supply compatibility. |
| Package | 32-Lead LFCSP (5x5 mm) | 32-Lead LFCSP (5x5 mm) | Identical package and footprint allow drop-in board compatibility between the two parts. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Same industrial temperature range means both suit the same environmental conditions. |
| Output Interface | CML | CML | Matching CML outputs ensure the same downstream driver/interface compatibility. |
| Input Sensitivity | ~5 mV p-p (typical) | ~5 mV p-p (typical) | Similar input sensitivity means comparable ability to recover weak signals from optical receivers. |

Frequently asked questions
What are the ADN2816ACPZ and ADN2815ACPZ-RL7?
Both are Analog Devices clock and data recovery (CDR) ICs for optical receiver applications. The ADN2816ACPZ is a continuous-rate 10 Mbps to 675 Mbps CDR with integrated limiting amplifier, supplied in a 32-lead LFCSP (ACPZ). The ADN2815ACPZ-RL7 is a continuous-rate 10 Mbps to 1.25 Gbps CDR in the same 32-lead LFCSP package, supplied in tape-and-reel form (RL7).
What is the maximum data rate of each device?
The ADN2816ACPZ supports continuous data rates from 10 Mbps to 675 Mbps. The ADN2815ACPZ-RL7 supports continuous data rates from 10 Mbps to 1.25 Gbps, giving it a higher upper data-rate limit than the ADN2816.
Are the ADN2816ACPZ and ADN2815ACPZ-RL7 pin-compatible?
Both devices are offered in the same 32-lead LFCSP package (ACPZ suffix), and their pinouts are defined by the respective Analog Devices datasheets. Pin function assignments should be verified against the specific datasheet revision before any layout or substitution decision, because the two parts are different CDR products with different rate ranges.
What is the difference between the ACPZ and ACPZ-RL7 suffixes?
The ACPZ suffix denotes the 32-lead LFCSP package. The -RL7 suffix on ADN2815ACPZ-RL7 indicates tape-and-reel packaging (7-inch reel) for automated assembly. The ADN2816ACPZ is specified without an -RL7 suffix in this comparison, so packaging form should be confirmed from the ordering guide of the respective datasheet.
Can the ADN2816ACPZ be replaced by the ADN2815ACPZ-RL7 in an existing design?
Not as a drop-in replacement without validation. Although both are continuous-rate CDRs in the same 32-lead LFCSP package, they are distinct products with different maximum data rates (675 Mbps vs 1.25 Gbps) and potentially different pin functions, register maps, and configuration requirements. Any substitution must be verified against both Analog Devices datasheets and the target design requirements.
What are typical applications for these CDR devices?
Both devices are intended for optical receiver modules and similar serial data links requiring clock and data recovery with an integrated limiting amplifier. The ADN2816ACPZ targets rates up to 675 Mbps, while the ADN2815ACPZ-RL7 extends to 1.25 Gbps, making it suitable for higher-rate optical and backplane links within its specified range.
Do both parts include an integrated limiting amplifier?
Yes. Both the ADN2816 and ADN2815 are specified by Analog Devices as continuous-rate clock and data recovery ICs with an integrated limiting amplifier, which quantizes the incoming signal before CDR processing. Detailed input sensitivity and output specifications should be taken from the respective datasheets.
Where can verified technical parameters be obtained?
Authoritative parameters, including data-rate range, package dimensions, pinout, supply requirements, and ordering information, are published in the official Analog Devices datasheets for the ADN2816 and ADN2815. Distributor listings from DigiKey, Mouser, or TTI can be used to confirm availability and packaging, but design-critical values should always be taken from the manufacturer datasheet.
