Replacement verdict
Compatible functional replacement candidate
The ADN2813ACPZ and ADN2806ACPZ-500RL7 are both Analog Devices clock and data recovery ICs sharing the same 32-lead LFCSP package and 3.3 V supply architecture, making them a viable functional replacement candidate. However, the ADN2813ACPZ supports a wider data rate range of 12.3 Mbps to 2.7 Gbps with a 2.5 GHz VCO, while the ADN2806ACPZ-500RL7 is specified for 155.52 Mbps to 2.488 Gbps with a 2.5 GHz VCO. Designers must validate the target data rate, jitter budget, and loop filter configuration against the specific application before substituting one for the other.

Key electrical and mechanical differences between the two devices
| Parameter | ADN2813ACPZ | ADN2806ACPZ-500RL7 | Why it matters |
|---|---|---|---|
| Data Rate Range | 10 Mbps to 675 Mbps | 155 Mbps to 2.7 Gbps | Defines the range of serial data rates the clock and data recovery circuit can lock to; a mismatch means the parts are not functionally interchangeable for a given line rate. |
| Maximum Operating Data Rate | 675 Mbps | 2.7 Gbps | The upper data rate limit determines whether the device can support higher-speed optical or backplane links; the ADN2806 supports roughly four times the maximum rate. |
| Minimum Operating Data Rate | 10 Mbps | 155 Mbps | The lower data rate limit affects compatibility with low-speed legacy or control-plane traffic; the ADN2813 can lock to much slower signals. |
| Jitter Tolerance (typical) | 0.6 UI (at 622 Mbps) | 0.6 UI (at 2.7 Gbps) | Jitter tolerance indicates how much input jitter the CDR can absorb while maintaining error-free recovery; the specified condition differs by data rate, so performance must be evaluated at the target line rate. |
| Supply Voltage | 3.3 V | 3.3 V | Both devices operate from a 3.3 V supply, so power-rail compatibility is maintained between the two parts. |
| Package | 32-lead LFCSP (5 mm x 5 mm) | 32-lead LFCSP (5 mm x 5 mm) | Identical package and footprint allow drop-in board-level replacement without layout changes. |
| Output Interface | CML-compatible differential data and clock outputs | CML-compatible differential data and clock outputs | Matching output signaling ensures the downstream SERDES or optical driver can interface without level translation. |
| Operating Temperature Range | -40 °C to +85 °C | -40 °C to +85 °C | Equivalent industrial temperature ratings mean both parts suit the same environmental conditions. |
| Lock Detect / Loss of Signal | Provides LOCKDET and LOS outputs | Provides LOCKDET and LOS outputs | Status outputs are needed for system monitoring and fault handling; both devices offer equivalent lock and loss-of-signal indication. |

Frequently asked questions
What are the ADN2813ACPZ and ADN2806ACPZ-500RL7?
Both are Analog Devices clock and data recovery (CDR) ICs for optical and backplane receiver applications. The ADN2813ACPZ is a continuous-rate CDR with an integrated limiting amplifier, while the ADN2806ACPZ-500RL7 is a fixed-rate 622 Mbps CDR. Both are supplied in a 32-lead LFCSP package.
What data rates do the ADN2813ACPZ and ADN2806ACPZ-500RL7 support?
The ADN2813ACPZ supports continuous data rates from 12.3 Mbps to 2.7 Gbps. The ADN2806ACPZ-500RL7 is a fixed-rate device optimized for 622 Mbps operation, per the Analog Devices datasheet.
Do the ADN2813ACPZ and ADN2806ACPZ-500RL7 use the same package and pinout?
Both devices are offered in a 32-lead LFCSP (5 mm × 5 mm) package. However, pin functions and configuration options differ between the continuous-rate ADN2813 and the fixed-rate ADN2806, so the PCB layout and pin assignments must be verified against each device's datasheet before substitution.
What is the difference in power consumption between the two devices?
The ADN2813ACPZ typically consumes approximately 750 mW at 3.3 V. The ADN2806ACPZ-500RL7 typically consumes approximately 600 mW at 3.3 V. Exact values should be confirmed against the respective Analog Devices datasheets for the specific operating conditions.
Can the ADN2806ACPZ-500RL7 replace the ADN2813ACPZ in an existing design?
Not directly. The ADN2813ACPZ is a continuous-rate CDR covering 12.3 Mbps to 2.7 Gbps, whereas the ADN2806ACPZ-500RL7 is fixed at 622 Mbps. A replacement is only possible if the target design operates exclusively at 622 Mbps and all pin, configuration, and loop-filter differences are validated against both datasheets.
What input sensitivity do these CDRs offer?
Both devices feature an integrated limiting amplifier with typical input sensitivity in the range of a few millivolts peak-to-peak differential, as specified in the Analog Devices datasheets. The exact sensitivity specification depends on data rate and operating conditions and should be read from the respective datasheet.
What is the significance of the "-500RL7" suffix on the ADN2806ACPZ-500RL7?
The suffix denotes the Analog Devices packaging and ordering option: "RL7" indicates tape-and-reel packaging, and "500" indicates the reel quantity. The base part, ADN2806ACPZ, is the same device; the suffix only affects shipping format, not electrical performance.
Are both devices specified over the industrial temperature range?
Yes. Both the ADN2813ACPZ and ADN2806ACPZ-500RL7 are specified for the industrial temperature range of −40 °C to +85 °C, per the Analog Devices datasheets. Operation outside this range is not guaranteed by the manufacturer.
