ADV3227ACPZ

Overview

The ADV3227ACPZ is a high-speed analog crosspoint switch manufactured by Analog Devices Inc. It features a 16 × 16 nonblocking matrix with buffered inputs and programmable high-impedance outputs. The device operates on ±5 V supplies, consuming 133 mA of idle current. It provides a -3 dB signal bandwidth exceeding 750 MHz at both 200 mV p-p and 2 V p-p levels. The internal gain is set to +2, and it drives 150 Ω loads with a slew rate of 2950 V/µs. Channel switching occurs in less than 20 ns with 1% settling time. Control is managed via serial or parallel digital interfaces using a 100-lead LFCSP package.

Feature Summary

• Features a 16 × 16 high-speed nonblocking analog switch array with buffered inputs
• Includes 16 independent output buffers capable of entering a high-impedance state to prevent off-channel loading
• Supports flexible control through either serial daisy-chaining or parallel programming for individual output updates
• Designed for low differential gain and phase error when driving composite video signals

Applications

• Routing of NTSC, PAL, S, SECAM, YUV, and RGB video signals
• Processing compressed video formats such as MPEG and wavelet
• Handling 3-level digital video signals including HDB3
• High-speed data communications and telecommunications systems

Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet specifications. Confirm the package type matches the 100-lead LFCSP format. Ensure the supply voltage requirements align with the specified ±5 V operation range before integration into the design.

Selection Notes

Select the ADV3227ACPZ when a fixed gain of +2 is required for the crosspoint application. Choose this model over the ADV3226 if signal amplification is necessary within the switching matrix. Ensure the system can accommodate the ±5 V dual power supply requirement and the specific thermal dissipation needs of the LFCSP package.

Part Context

This component belongs to the ADV3226/ADV3227 series of analog crosspoint switches from Analog Devices. It is pinout and functionally equivalent to the AD8114/AD8115 series. The device serves as a building block for constructing larger multicast-capable crosspoint arrays due to its buffered input architecture which isolates inputs from output loading effects.

Replacement Considerations

The ADV3226ACPZ is a direct functional substitute within the same family, differing only in having a gain of +1 instead of +2. Designers must verify that the system signal levels are compatible with the unity gain configuration if substituting the ADV3226.
