Product details
Overview
ADN4605ABPZ from Analog Devices is a 40 × 40 fully differential, nonblocking digital crosspoint switch IC optimized for NRZ signaling up to 4.25 Gbps per port. It features adjustable receive equalization (3/6/12 dB), programmable transmit preemphasis/deemphasis, 50 Ω on-chip I/O termination, and dual connection map support - deployed in high-speed serial backplane routing, fiber optic switching, and digital video infrastructure.
For engineers reviewing the ADN4605ABPZ datasheet, ADN4605ABPZ pinout, ADN4605ABPZ application, or ADN4605ABPZ equivalent, this device serves as a protocol-agnostic, low-jitter (<25 ps typ) switching solution for HDMI/DVI/DisplayPort, XAUI, Fibre Channel, InfiniBand®, and OC-48 systems requiring deterministic latency and channel-to-channel skew <200 ps.
Technical Context
The ADN4605ABPZ implements an asynchronous 40 × 40 crossbar matrix with independent lane-level control via serial (I²C/SPI) or parallel interfaces. Each of its 40 differential input channels supports DC–4.25 Gbps NRZ data with configurable equalization to compensate up to 40 inches of FR4 trace loss; each output provides programmable CML swing (670–875 mV p-p diff) and preemphasis (0–9.5 dB boost).
It integrates dual-rank connection mapping for dynamic reconfiguration without traffic interruption, polarity inversion per lane for PCB routing flexibility, and on-die 50 Ω termination with disable capability. Power delivery supports flexible 2.5 V to 3.3 V supplies across VCC, DVCC, VTTIA/VTTIB, and VTTOA/VTTOB rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Data Rate | DC to 4.25 Gbps per port - supports full-rate NRZ operation for XAUI, 4× Fibre Channel, and DisplayPort 1.2 links. |
| Jitter Performance | <25 ps typical residual deterministic jitter at 4.25 Gbps with 12 dB EQ - enables reliable signal integrity over lossy backplanes. |
| Input Sensitivity | 50–2000 mV p-p differential swing - accommodates low-amplitude PECL/CML sources and ac-coupled legacy interfaces. |
| Output Swing | 670–875 mV p-p differential (at dc, 0 dB PE) - matches standard CML receiver thresholds with 16–32 mA per-port drive capability. |
| Propagation Delay | 920 ps input-to-output - ensures predictable timing budgeting in synchronous multi-lane systems. |
| Channel Skew | <200 ps max - maintains inter-lane alignment critical for 8b10b-encoded protocols like Fibre Channel and InfiniBand®. |
| Supply Range | VCC: 2.25–3.6 V; DVCC: 3.0–3.6 V; VTTx: 2.5 V to VCC + 0.3 V - enables mixed-voltage system integration with margin. |
Pinout & Package
The ADN4605ABPZ is housed in a 35 mm × 35 mm, 352-ball BGA package (BP-352-2) with 0.8 mm pitch, designed for high-density PCB layouts and thermal management in industrial and telecom applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IP[39:0], IN[39:0] | Differential high-speed inputs | Accept PECL/CML-compatible ac- or dc-coupled NRZ signals; support 50 mV–2 V p-p swing with internal 50 Ω termination enable/disable. |
| OP[39:0], ON[39:0] | Differential high-speed outputs | Programmable CML outputs with adjustable swing and preemphasis; each pair drives 50 Ω differential loads. |
| VTTIA/VTTIB, VTTOA/VTTOB | I/O termination supplies | Separate analog rails for input/output termination biasing - allow independent voltage setting and noise isolation. |
| I²C/SPI/UPDATE, SER/PAR, CS, RE, WE | Control interface selection & strobes | Enable three concurrent configuration modes: I²C slave (SCL/SDA), SPI (SCK/SDI/SDO), or 8-bit parallel (ADDR/DATA/RE/WE). |
| RESET | Asynchronous reset | Active-low signal that clears all configuration registers and forces default switch state - requires external pull-up to DVCC. |
Key Features
| Feature | Design Value |
|---|---|
| Adjustable receive equalization | 3 dB / 6 dB / 12 dB boost settings - compensates deterministic ISI from up to 40 inches of FR4 at 4.25 Gbps without external components. |
| Programmable transmit preemphasis | 0–9.5 dB adjustable boost - restores high-frequency content degraded by channel loss, enabling longer trace reach. |
| Dual-rank connection mapping | Two independent switch matrices (Map 0/Map 1) - allows seamless failover or dynamic reconfiguration without packet loss. |
| Per-lane polarity inversion | Software-controlled inversion on any input/output pair - eliminates manual PCB trace swapping during layout iteration. |
| On-chip 50 Ω differential termination | Configurable enable/disable per I/O bank - reduces BOM count and improves impedance matching versus discrete termination networks. |
Applications
| Video Routing Infrastructure | Fiber Optic Network Switching |
|---|---|
Use Scenario: Aggregating and distributing uncompressed 4K/60Hz HDMI or DisplayPort 1.2 streams across multiple monitors or capture devices in broadcast studios.

Equivalent & Alternatives
The following parts are listed as comparable options for similar digital crosspoint switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4824ETL+ | 8×8 architecture, max 3.2 Gbps per port, integrated CDR, no dual-map support | Targeted at lower-density, retimed applications (e.g., PCIe Gen2 fanout); lacks FR4 compensation beyond 20 inches | Select when deterministic jitter <15 ps and embedded CDR are required - not suitable for 40×40 or 4.25 Gbps unretimed routing. |
| DS10BR150TSDX | 10×10, 4.25 Gbps, no equalization or preemphasis, fixed 800 mV p-p output swing | Designed for short-reach point-to-point interconnects (e.g., GPU-to-switch); no backplane loss compensation capability | Choose for cost-sensitive, low-complexity routing where channel loss <15 dB - cannot replace ADN4605ABPZ in FR4-heavy systems. |
Compared with MAX4824ETL+ and DS10BR150TSDX, the ADN4605ABPZ uniquely delivers 40×40 scale, 4.25 Gbps per port with adaptive equalization and dual-rank mapping - making it the only option among the three for large-scale, unretimed, loss-compensated backplane switching in telecom and broadcast infrastructure.

FAQ
What is the maximum supported data rate per channel for the ADN4605ABPZ?
The ADN4605ABPZ supports NRZ data rates from DC up to 4.25 Gbps per channel, verified under PRBS7 pattern testing at 25°C with ac-coupled inputs and outputs. This rating applies across the full operating temperature range (−40°C to +85°C) and is maintained with enabled receive equalization and transmit preemphasis.
Does the ADN4605ABPZ require external termination resistors?
No, the ADN4605ABPZ integrates 50 Ω differential on-chip termination for both inputs and outputs, configurable per bank via register control. External termination is optional and used only when disabling internal termination for specific biasing or AC-coupling configurations.
Which control interfaces does the ADN4605ABPZ support?
The ADN4605ABPZ supports three concurrent control interfaces: I²C (slave mode, up to 500 kHz), SPI (mode 0/3, up to 10 MHz), and parallel (8-bit address/data bus with RE/WE strobes). Interface selection is hardware-configured via SER/PAR, I²C/SPI, and UPDATE pins.
Can the ADN4605ABPZ operate with mixed supply voltages?
Yes - the ADN4605ABPZ supports independent supply domains: VCC (2.25–3.6 V) for core analog circuitry, DVCC (3.0–3.6 V) for digital logic, and separate VTTIA/VTTIB and VTTOA/VTTOB rails (2.5 V to VCC + 0.3 V) for I/O termination biasing - enabling robust mixed-voltage system integration.
Is the ADN4605ABPZ pin-compatible with other members of the ADN460x family?
No - the ADN4605ABPZ uses a unique 352-ball BGA (BP-352-2) package with specific pin assignments for 40×40 I/O. Other ADN460x variants (e.g., ADN4604) have different channel counts, pinouts, and package footprints; direct PCB replacement is not supported.
