GENERAL DESCRIPTION

The AD8176 is a high speed, triple 16 × 9 video crosspoint switch matrix. It supports 1600 × 1200 RGB displays @ 85 Hz refresh rate, by offering a 450 MHz bandwidth and a slew rate of 1650 V/µs. With −82 dB of crosstalk and −90 dB isolation (@ 5 MHz), the AD8176 is useful in many high speed video applications.
The AD8176 supports two modes of operation: differential-in to differential-out mode with sync-on CM signaling passed through the switch and differential-in to differential-out mode with CM signaling removed through the switch. The output

Specifications subject to change without notice. No license is granted by implication or otherwise under any patent or patent rights of Analog Devices.

CM and black level can be conveniently set via external pins. The outputs can be used single-ended in conjunction with decoded H and V outputs to drive a monitor directly.
The independent output buffers of the AD8176 can be placed into a high impedance state to create larger arrays by paralleling crosspoint outputs. Inputs can be paralleled as well. The AD8176 offers both serial and a parallel programming modes.
The AD8176 is packaged in a fully populated 26 × 26 ball PBGA package and is available over the extended industrial temperature range of −40°C to +85°C.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those indicated in the operational section of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.

THERMAL RESISTANCE

θJA is specified for the worst-case conditions, that is, a device
soldered in a circuit board for surface-mount packages.
Table 13. Thermal Resistance
Package Type θJA Unit
PBGA 15 °C/W

POWER DISSIPATION

The AD8176 is operated with ±2.5 V or +5 V supplies and can drive loads down to 100 , resulting in a large range of possible power dissipations. For this reason, extra care must be taken derating the operating conditions based on ambient temperature.
Packaged in a 676-lead BGA, the AD8176 junction-to-ambient thermal impedance (θ the maximum allowed junction temperature of the die should not exceed 150°C. Temporarily exceeding this limit may cause a shift in parametric performance due to a change in stresses exerted on the die by the package. Exceeding a junction tem­perature of 175°C for an extended period can result in device failure.
Figure 4 shows the range of allowed internal die power dissipations that meet these conditions over the −40°C to +85°C ambient temperature range. When using external load power in the Maximum Power calculation, but do include load current dropped on the die output transistors.
