Analog Devices Inc. AD8150ASTZ

Overview

AD8150ASTZ from Analog Devices is a 33 × 17 fully differential, nonblocking digital crosspoint switch IC designed for high-speed serial data routing in HD/SD video and optical network infrastructure. It supports >1.5 Gbps NRZ data rate per port, operates from ±3.3 V or ±5 V supplies, delivers <50 ps p-p jitter, and drives backplanes directly without heat sinks. It is used in OC-24 fiber switch fabric and HDTV signal distribution systems.

For engineers reviewing the AD8150ASTZ datasheet, AD8150ASTZ pinout, AD8150ASTZ application, or AD8150ASTZ equivalent, this page provides verified functional specifications, industrial-temperature LQFP package details, PECL/ECL-compatible I/O architecture, dual-rank latch control interface timing, and real-world substitution guidance for video and telecom switching designs.

Technical Context

The AD8150ASTZ implements a fully differential 33 × 17 switch matrix with two-stage 7-bit latching (first-rank write + second-rank update), enabling glitch-free reconfiguration. Its signal path uses PECL/ECL-compatible differential inputs and outputs with programmable output current via REF/VEEREF pins, supporting termination optimization across 50 Ω loads.

Control logic operates at CMOS/TTL levels (3 V to 5 V), independent of analog supply rails. The double-row latch architecture allows broadcast programming (all 17 outputs to one input) and individual output disable-critical for busing and large-array expansion in modular switching systems.

Key Specifications

Pinout & Package

AD8150ASTZ is housed in a 184-lead LQFP (16 mm × 16 mm, 0.5 mm pitch) with exposed thermal pad, rated for industrial temperature range (0°C to 85°C). Power pins are distributed across multiple corners to minimize ground bounce; differential I/Os are arranged in matched-length pairs for skew control.

FAQ

What is the maximum supported data rate for AD8150ASTZ per channel?

The AD8150ASTZ supports a maximum data rate of 1.5 Gbps per port using NRZ encoding, as confirmed in Table 1 of the Rev. A datasheet. This rating applies across the full industrial temperature range (0°C to 85°C) with <50 ps p-p jitter and 100 ps rise/fall times, making it suitable for SMPTE 292M HD-SDI and OC-24 SONET applications. The device maintains this performance with proper termination and layout per Figure 25 test circuit.

Does AD8150ASTZ support both PECL and ECL logic levels?

Yes, AD8150ASTZ supports both PECL and ECL signaling through flexible supply configuration: for PECL operation, use VCC = +3.3 V to +5 V and VEE = 0 V; for ECL, use VEE = −5 V to −3.3 V and VCC = 0 V. Input voltage swing is specified at 200–1000 mV p-p differential, and output swing reaches 800 mV p-p - verified in Table 1 and Figures 23–24 under both supply conditions.

How is output current programmed on AD8150ASTZ?

Output current on AD8150ASTZ is programmed via an external resistor connected between REF and VEEREF pins, as described in "Output Current Set Pin (REF)" section (page 24) and Figure 25. The resistor value sets output current from 5 mA to 25 mA, enabling precise termination matching to 50 Ω loads. Typical value is 1.54 kΩ for 16 mA output, yielding VOH = −0.8 V and VOL = −1.8 V with VEE = −3.3 V.

What is the function of the dual-rank latch architecture in AD8150ASTZ?

The dual-rank latch architecture in AD8150ASTZ separates configuration storage (first-rank latches) from active switching (second-rank latches). This allows new routing configurations to be written without disrupting live signal paths. Only upon assertion of the UPDATE signal does the switch matrix atomically adopt the new settings - preventing glitches, metastability, or transient shorts during reprogramming, as detailed in Tables 4–5 and Figure 31.

Is AD8150ASTZ compatible with standard 184-lead LQFP footprints?

Yes, AD8150ASTZ uses a standard 184-lead LQFP package (16 mm × 16 mm, 0.5 mm pitch) with JEDEC MS-026AC specification, as shown in Figure 4 and "Outline Dimensions" (page 42). Pin 1 indicator and thermal pad layout match industry-standard land patterns. No custom footprint is required - designers may use existing LQFP-184 templates with 0.5 mm pitch and 0.65 mm solder mask defined pads.
