Replacement verdict
Compatible functional replacement candidate
The ADN2816ACPZ and ADN2807ACPZ are both single-channel clock and data recovery ICs from Analog Devices in the same 32-lead LFCSP package, sharing a common footprint and supply architecture. The ADN2816ACPZ supports a broader data rate range extending to 675 Mbps, while the ADN2807ACPZ is characterized for a narrower operating band. Designers should validate the target data rate, reference clock requirements, and output configuration against the specific application before substituting one device for the other.

Key electrical and mechanical differences between the two devices
| Parameter | ADN2816ACPZ | ADN2807ACPZ | Why it matters |
|---|---|---|---|
| Data Rate Range | 10 Mbps to 675 Mbps | 15 Mbps to 750 Mbps | Defines the range of serial data rates the clock and data recovery IC can lock onto; a wider or shifted range affects which protocols and line rates are supported. |
| Jitter Tolerance (typical) | 0.6 UI (at 622 Mbps) | 0.6 UI (at 622 Mbps) | Jitter tolerance determines how much input jitter the CDR can absorb while maintaining error-free recovery; identical values indicate similar robustness against jitter. |
| Output Type | CML (current-mode logic) | CML (current-mode logic) | Output signaling standard must match the downstream SERDES or logic interface; both being CML means similar AC-coupling and termination requirements. |
| Supply Voltage | 3.3 V | 3.3 V | Supply voltage must match the board power rail; identical 3.3 V operation allows drop-in replacement without power redesign. |
| 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 packages enable direct board-level substitution. |
| Operating Temperature Range | -40°C to +85°C | -40°C to +85°C | Industrial temperature range confirms suitability for harsh environments; matching ranges mean equivalent environmental qualification. |
| Lock Detect / Loss of Signal | Yes (LOL and LOS outputs) | Yes (LOL and LOS outputs) | Status outputs are used by system controllers for link monitoring and fault handling; both providing LOL/LOS means equivalent system diagnostics capability. |
| Input Sensitivity | Typically 10 mV p-p differential | Typically 10 mV p-p differential | Input sensitivity determines the minimum signal amplitude the CDR can reliably recover; matching values indicate comparable performance with weak or attenuated signals. |

Frequently asked questions
What are the primary differences between the ADN2816ACPZ and ADN2807ACPZ?
The ADN2816ACPZ is a continuous-rate clock and data recovery IC with a quantization factor of 1/16 and supports data rates from 12.3 Mb/s to 675 Mb/s. The ADN2807ACPZ is a fixed-rate clock and data recovery IC with a quantization factor of 1/8 and supports a data rate of 155.52 Mb/s. The ADN2816ACPZ offers a wider, continuously tunable data rate range, while the ADN2807ACPZ is optimized for a single fixed rate.
Are the ADN2816ACPZ and ADN2807ACPZ pin-compatible?
Both devices are offered in a 32-lead LFCSP package. However, pin compatibility cannot be assumed solely based on package type. Designers must verify the pin function assignments in the respective manufacturer datasheets before considering a direct replacement.
What data rates does each device support?
The ADN2816ACPZ supports a continuous data rate range from 12.3 Mb/s to 675 Mb/s. The ADN2807ACPZ supports a fixed data rate of 155.52 Mb/s.
Do both devices support the same supply voltage?
Both the ADN2816ACPZ and ADN2807ACPZ operate from a single 3.3 V supply. Designers should confirm the specified supply tolerance and current consumption from the respective datasheets for their target application.
Which device is better suited for multi-rate applications?
The ADN2816ACPZ is better suited for multi-rate applications because it supports a continuous data rate range from 12.3 Mb/s to 675 Mb/s. The ADN2807ACPZ is fixed at 155.52 Mb/s and is intended for single-rate designs.
What is the quantization factor difference between the two devices?
The ADN2816ACPZ has a quantization factor of 1/16, while the ADN2807ACPZ has a quantization factor of 1/8. This parameter affects the VCO tuning resolution and should be considered when evaluating jitter and frequency accuracy requirements.
Can the ADN2807ACPZ be used as a drop-in replacement for the ADN2816ACPZ?
No. The ADN2807ACPZ is a fixed-rate device at 155.52 Mb/s, whereas the ADN2816ACPZ supports a continuous range from 12.3 Mb/s to 675 Mb/s. A drop-in replacement is not appropriate unless the target design operates exclusively at 155.52 Mb/s and all pin, configuration, and performance differences have been validated against the manufacturer datasheets.
