Replacement verdict
Compatible functional replacement candidate
The ADN2816ACPZ and ADN2813ACPZ-RL7 are both single-channel clock and data recovery ICs from Analog Devices in the same 32-lead LFCSP package, sharing a common core architecture and supply domain. The ADN2816ACPZ operates across a narrower data rate range with a different output interface configuration, while the ADN2813ACPZ-RL7 extends the supported data rate span and output options. Because the two devices are not pin-for-pin identical in output signaling and rate coverage, board-level validation of the output interface and operating data rate is required before substitution, but the shared package, supply, and functional category make the ADN2813ACPZ-RL7 a viable functional replacement candidate for the ADN2816ACPZ in appropriately validated designs.

Key electrical and mechanical differences between the two devices
| Parameter | ADN2816ACPZ | ADN2813ACPZ-RL7 | Why it matters |
|---|---|---|---|
| Data Rate Range | 10 Mbps to 675 Mbps | 12.3 Mbps to 675 Mbps | Defines the lowest supported bit rate; the ADN2816 can lock to slower signals (10 Mbps) than the ADN2813 (12.3 Mbps), affecting compatibility with legacy or low-speed protocols. |
| Jitter Tolerance (typical) | 0.6 UI at 10 Mbps | 0.6 UI at 12.3 Mbps | Jitter tolerance determines how much timing distortion the CDR can absorb while maintaining error-free lock; the specified rate differs because the minimum operating rate differs. |
| Output Data Interface | CML (current-mode logic) | CML (current-mode logic) | The output driver type must match the downstream SERDES or receiver input; both use CML, so board-level interfacing is equivalent. |
| Supply Voltage | 3.3 V | 3.3 V | Supply voltage must match the system rail; both operate from a single 3.3 V supply, allowing drop-in power compatibility. |
| Package | 32-lead LFCSP (5 mm x 5 mm) | 32-lead LFCSP (5 mm x 5 mm) | Package footprint and pinout determine PCB layout compatibility; identical LFCSP packages allow the same land pattern to be reused. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Industrial temperature range ensures reliable operation in harsh environments; both parts share the same range. |
| Lock Detect / Loss of Lock Indicator | Yes (LOL pin) | Yes (LOL pin) | A loss-of-lock indicator is essential for system monitoring and fault handling; both devices provide this signal. |
| Reference Clock Input | Optional external reference supported | Optional external reference supported | An external reference clock improves lock acquisition and holdover behavior; both parts support it, preserving system design flexibility. |

Frequently asked questions
What are the ADN2816ACPZ and ADN2813ACPZ-RL7?
Both are Analog Devices clock and data recovery (CDR) ICs for optical receiver applications. The ADN2816ACPZ is a continuous-rate CDR with a specified operating range of 10 Mbps to 675 Mbps, while the ADN2813ACPZ-RL7 is a continuous-rate CDR specified for 12.3 Mbps to 675 Mbps. Both are offered in a 32-lead LFCSP package.
What is the difference in data rate range between the ADN2816ACPZ and ADN2813ACPZ-RL7?
The ADN2816ACPZ is specified for a lower bound of 10 Mbps up to 675 Mbps. The ADN2813ACPZ-RL7 is specified for a lower bound of 12.3 Mbps up to 675 Mbps. The upper limit is the same for both devices.
Are the ADN2816ACPZ and ADN2813ACPZ-RL7 pin-compatible?
Both devices are supplied in the same 32-lead LFCSP package, and Analog Devices documents them as pin-compatible CDR devices within the same family. Designers should still confirm the pin functions and any application-specific connections against the respective datasheets before substituting one for the other.
What is the difference between the ACPZ and ACPZ-RL7 suffixes?
The ACPZ suffix denotes the 32-lead LFCSP package in the standard ordering format. The -RL7 suffix indicates tape-and-reel packaging with a 7-inch reel. The silicon device itself is the same; only the packaging and shipment format differ.
Do both devices support the same supply voltage and temperature range?
Both the ADN2816ACPZ and ADN2813ACPZ-RL7 operate from a single 3.3 V supply and are specified over the industrial temperature range of -40°C to +85°C, consistent with Analog Devices documentation for these CDR products.
Can the ADN2816ACPZ and ADN2813ACPZ-RL7 be used interchangeably in an existing design?
Because both are continuous-rate CDRs in the same 32-lead LFCSP package with overlapping 3.3 V operation and industrial temperature ratings, they are candidates for substitution. However, the lower data-rate limit differs (10 Mbps vs 12.3 Mbps), so the target application's minimum data rate must be checked against the selected device's specification before interchange.
What are typical applications for these CDR devices?
These continuous-rate clock and data recovery ICs are intended for optical receiver modules and serial data links, including SONET/SDH, Gigabit Ethernet, Fibre Channel, and other continuous-rate serial protocols within their specified data-rate ranges.
