Product details
Overview
AD8152JBPZ from Analog Devices is a 34 × 34 fully differential, nonblocking asynchronous digital crosspoint switch IC designed for high-speed serial routing in backplane and optical network infrastructure. It supports 3.2 Gbps per port NRZ data rate, delivers 45 ps p-p channel jitter, features 50 Ω on-chip I/O termination, and operates across 2.5 V to 3.3 V supply range - enabling direct driving of OC-48-compliant backplanes with FEC.
For engineers reviewing the AD8152JBPZ datasheet, AD8152JBPZ pinout, AD8152JBPZ application, or AD8152JBPZ equivalent, key selection criteria include its 34-input/34-output differential switching matrix, programmable output swing (100–1600 mV p-p), dual-rank latch control architecture, LVTTL/LVCMOS-compatible interface, and industrial-temperature-rated 256-ball BGA_ED package.
Technical Context
The AD8152JBPZ implements an asynchronous, fully differential 34 × 34 switch matrix with independent input and output termination (VTTI/VTTO) and dual-rank latching-separating configuration setup (first rank) from atomic broadcast update (second rank). Its control logic accepts 7-bit address (A6–A0) and 6-bit data (D5–D0) via LVTTL/LVCMOS inputs, supporting transparent write, single-output readback, and global reset functions.
Signal integrity is maintained through on-die 50 Ω termination, low 45 ps p-p jitter, sub-800 ps propagation delay, and matched ±120 ps delay skew across channels. The device drives backplanes directly without external AC coupling or termination, with output current programmable from 2 mA to 32 mA per differential pair.
Key Specifications

Pinout & Package
AD8152JBPZ is housed in a 256-ball enhanced-density ball grid array (BGA_ED) package, pin-compatible with BP-256-3 footprint, rated for industrial temperature range (0°C to +85°C). Power delivery is distributed across multiple VCC (positive supply), VEE (negative supply), VTTI (input termination), and VTTO (output termination) balls to minimize noise and ensure stable high-speed operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN00P–IN33P / IN00N–IN33N | Differential Input Pairs (68 total) | High-speed NRZ data inputs; accept 50–1000 mV p-p single-ended swing with common-mode range VEE+0.8 V to VCC+0.2 V. |
| OUT00P–OUT33P / OUT00N–OUT33N | Differential Output Pairs (68 total) | Programmable current outputs (2–32 mA); support 100–1600 mV p-p swing into 50 Ω loads. |
| A0–A6, D0–D5 | Control Address & Data Bus | 7-bit address (MSB A6 selects connection vs. current mode) and 6-bit data bus for configuring routing or output drive strength. |
| CS, WE, RE, UPDATE, RESET | Asynchronous Control Strobes | Enable first-rank write (WE), second-rank update (UPDATE), readback (RE), chip select (CS), and global reset (RESET) with nanosecond-level timing margins. |
| VCC / VEE / VTTI / VTTO | Power & Termination Supplies | Dedicated rails isolate analog signal paths: VTTI powers input termination; VTTO powers output termination; VCC/VEE power core logic and drivers. |
Key Features
| Feature | Design Value |
|---|---|
| Fully differential 34×34 switch matrix | Eliminates common-mode noise and crosstalk; enables smaller voltage swings and higher noise immunity in dense backplane layouts. |
| Programmable output current (2–32 mA) | Per-channel drive strength tuning optimizes signal integrity across varying trace lengths, connectors, and load conditions without redesign. |
| Dual-rank latch architecture | Decouples configuration loading (first rank) from atomic broadcast update (second rank), preventing partial reconfiguration glitches during live traffic. |
| On-chip 50 Ω termination | Reduces component count, PCB area, and layout complexity while improving impedance consistency over process, voltage, and temperature. |
| LVTTL/LVCMOS-compatible control interface | Direct interfacing with FPGA or ASIC GPIOs at 2.5 V or 3.3 V logic levels - no level-shifting circuitry required. |

| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD8151ACPZ | 32 × 32 array, 2.5 Gbps max data rate, same BGA-256 package and control interface. | Lower port count and bandwidth; suitable for cost-sensitive OC-12 or 1 GbE systems where 34×34 and 3.2 Gbps are not required. | Select AD8151ACPZ when system scale and speed budget allow reduction in channel count and data rate. |
| MAX4825ETL+ | 16 × 16 array, 3.125 Gbps, 40-pin TQFN; lacks on-chip termination and dual-rank latches. | Targeted at compact, lower-port-count applications such as embedded media processors or test equipment; requires external termination and careful timing management. | Choose MAX4825ETL+ only for space-constrained designs accepting trade-offs in integration and configurability. |

FAQ
What is the maximum supported data rate per channel for the AD8152JBPZ?
The AD8152JBPZ supports up to 3.2 Gbps per port using Nonreturn-to-Zero (NRZ) encoding. This specification is validated under typical operating conditions (25°C, VCC = 2.5 V to 3.3 V, 50 Ω load, 800 mV p-p differential output swing) and enables compliance with SONET/SDH OC-48 standards including forward error correction. The AD8152JBPZ maintains this rate across all 34 input and 34 output channels simultaneously.
Does the AD8152JBPZ require external termination resistors?
No, the AD8152JBPZ integrates 50 Ω ±7% on-chip termination for both inputs and outputs, eliminating the need for external resistors. Input termination is powered by VTTI, and output termination by VTTO - allowing independent biasing to optimize signal integrity. This integration reduces PCB area, component count, and layout sensitivity while maintaining impedance stability over temperature and voltage variation.
How does the dual-rank latch architecture of the AD8152JBPZ improve system reliability?
The AD8152JBPZ uses dual-rank latches to separate configuration loading (first rank) from atomic broadcast update (second rank). This prevents partial or inconsistent routing states during live traffic - ensuring all outputs switch simultaneously upon UPDATE assertion. The architecture supports glitch-free reconfiguration, essential for carrier-grade telecom and broadcast video systems where uninterrupted signal flow is mandatory. This behavior is intrinsic to the AD8152JBPZ's control protocol and timing specifications.
What is the operating temperature range for the AD8152JBPZ?
The AD8152JBPZ is specified for industrial temperature operation from 0°C to +85°C ambient. This range is guaranteed for all electrical parameters in the datasheet, including 3.2 Gbps data rate, 45 ps p-p jitter, and 50 Ω termination accuracy. The device's thermal resistance (θJA = 9.2°C/W) and maximum junction temperature (175°C) are validated per JEDEC standards, supporting reliable deployment in fan-cooled telecom chassis and broadcast equipment enclosures.
Can the AD8152JBPZ drive a backplane directly without additional signal conditioning?
Yes, the AD8152JBPZ is explicitly designed to drive backplanes directly. Its fully differential architecture, on-chip 50 Ω termination, programmable 100–1600 mV p-p output swing, and low 45 ps p-p jitter enable clean signal transmission across lossy FR4 traces up to 20 inches. The datasheet confirms direct backplane driving capability for OC-48 with FEC, and no external AC coupling capacitors, equalizers, or repeaters are required when used within specified layout guidelines.
