Product details
Overview
ADN8102ACPZ-R7 from Analog Devices is a quad bidirectional CX4/backplane equalizer IC optimized for NRZ data up to 3.75 Gbps, featuring programmable input equalization (up to 22 dB at 1.875 GHz) and output pre-emphasis (up to 12 dB), with integrated 50 Ω on-chip termination and loss-of-signal detection. It supports chassis-to-chassis interconnects in 10GBase-CX4, InfiniBand®, and XAUI™ systems.
For engineers reviewing the ADN8102ACPZ-R7 datasheet, ADN8102ACPZ-R7 pinout, ADN8102ACPZ-R7 application, or ADN8102ACPZ-R7 equivalent, this device delivers deterministic jitter < 33 ps p-p at 3.75 Gbps, channel-to-channel skew < 50 ps, and flexible 1.8 V–3.3 V core supply operation - critical for high-speed serial link integrity validation and FR4/CX4 cable compensation.
Technical Context
The ADN8102ACPZ-R7 implements two independent 4-lane ports (Port A and Port B), each with fully asynchronous receive equalization and transmit pre-emphasis paths supporting dc-to-3.75 Gbps NRZ data. Its multizero continuous-time equalizer compensates frequency-dependent loss in FR4 backplanes (up to 40 inches) and CX4 cables (up to 30 m input / 15 m output).
Control is configurable via toggle pins, I²C interface (7-bit slave address with ADDR[1:0] pin-selectable LSBs), or mixed mode; all eight differential CML-compatible I/O channels support P/N pair inversion and per-lane loopback. The device operates across −40°C to +85°C with 50 Ω on-chip termination referenced to user-defined VTTI/VTTO supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Max Data Rate | 3.75 Gbps per channel - enables full-rate 10GBase-CX4 and XAUI™ compliance without retiming. |
| Input Equalization Boost | Up to 22 dB at 1.875 GHz - compensates up to 30 m of 24 AWG CX4 cable or 40 inches of FR4 at 3.75 Gbps. |
| Output Pre-Emphasis Boost | Up to 12 dB at 1.875 GHz - extends reach to 15 m CX4 or 40 inches FR4 on transmit side. |
| Deterministic Jitter | 33 ps p-p at <3.75 Gbps (BER = 1×10⁻¹²) - ensures robust eye opening in high-loss channels. |
| Channel Skew | 50 ps max - maintains lane alignment for multi-lane protocols like InfiniBand® and CPRI™. |
| Supply Range | VCC = 1.7 V to 3.6 V - supports both 1.8 V and 3.3 V core logic domains with single-supply simplicity. |

Key Features
| Feature | Design Value |
|---|---|
| Programmable Input Equalization | 8 discrete gain settings (1.5–22 dB, 2.5 dB steps) optimized for skin-effect vs. dielectric-loss dominated channels. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed serial equalizer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX3802ETM+ | Single-port, 3.2 Gbps max, fixed 15 dB EQ, no I²C interface - pin-strapped only. | Limited to lower-speed SRIO or proprietary backplanes; lacks dual-port flexibility and programmability. | Choose when cost-sensitive, single-lane, non-reconfigurable links dominate the BOM. |
| DS100BR210SQ/NOPB | 2-channel, 10.3125 Gbps, integrated CDR, 2.5 V supply only, no input EQ - redriver-only function. | Targets optical module interfaces (SFP+, QSFP) requiring clock recovery; not suitable for passive cable equalization. | Prefer for >3.75 Gbps retiming applications where jitter cleanup is mandatory and CDR functionality is required. |
Compared with MAX3802ETM+ and DS100BR210SQ/NOPB, the ADN8102ACPZ-R7 uniquely combines quad-lane bidirectional equalization, dual-port independence, I²C configurability, and 3.75 Gbps operation in a single 64-lead LFCSP - making it the only solution validated for 10GBase-CX4 and InfiniBand® chassis links with field-adjustable compensation.

FAQ
What is the maximum supported data rate for ADN8102ACPZ-R7?
The ADN8102ACPZ-R7 supports a maximum data rate of 3.75 Gbps per channel for NRZ data, as verified in the Rev. C datasheet under Dynamic Performance specifications. This rate is validated across all eight differential lanes with deterministic jitter ≤33 ps p-p and residual jitter ≤0.24 UI at full speed, ensuring compatibility with 10GBase-CX4 and XAUI™ standards. Operation above 3.75 Gbps is not characterized or guaranteed.
Does ADN8102ACPZ-R7 support both AC- and DC-coupled inputs?
Yes, the ADN8102ACPZ-R7 supports both AC- and DC-coupled differential CML inputs, as confirmed in the General Description and Input Characteristics sections of the datasheet. Input termination is provided by on-chip 50 Ω resistors referenced to VTTI, which can be set from (VEE + 0.4 V) to (VCC + 0.5 V), enabling direct interfacing with 1.8 V, 2.5 V, or 3.3 V logic families without external biasing networks.
How is the I²C address configured for ADN8102ACPZ-R7?
The ADN8102ACPZ-R7 uses a 7-bit I²C slave address where the upper five bits are fixed as b10010, and the lower two bits are determined by the logic levels on ADDR0 and ADDR1 pins, as specified in the I²C Control Interface section. This allows up to four ADN8102ACPZ-R7 devices on the same bus. The default address (ADDR[1:0] = 00) is 0x48, and all addresses are documented in Table 5 of the Rev. C datasheet.
What is the purpose of the LB (Loopback) pin on ADN8102ACPZ-R7?
The LB pin on ADN8102ACPZ-R7 provides hardware-controlled loopback for system-level debug and test, as described in the Functional Block Diagram and Theory of Operation sections. When asserted, it routes each receiver input directly to its corresponding transmitter output within the same port, bypassing equalization and pre-emphasis blocks. This enables rapid physical-layer validation without host controller involvement.
Can ADN8102ACPZ-R7 operate with different supply voltages on VCC and DVCC?
Yes, the ADN8102ACPZ-R7 supports independent core (VCC) and digital I/O (DVCC) supplies: VCC ranges from 1.7 V to 3.6 V, while DVCC must be ≤ (VCC + 1.3 V) and is typically 3.3 V. This separation allows low-power core logic (e.g., 1.8 V) to coexist with 3.3 V I²C and control signaling, as confirmed in the Power Supply table (Page 4) and Absolute Maximum Ratings (Page 6) of the Rev. C datasheet.
