APPLICATIONS

Routing of High Speed Signals Including:

Video (NTSC, PAL, S, SECAM, YUV, RGB)

Compressed Video (MPEG, Wavelet)

3-Level Digital Video (HDB3)

Datacomms

The AD8114 /AD8115 include 16 independent output buffers

that can be placed into a high impedance state for paralleling

crosspoint outputs so that off channels do not load the output

bus. The AD8114 has a gain of +1, while the AD8115 offers

a gain of +2. They operate on voltage supplies of ±5 V while

consuming only 70 mA of idle current. The channel switching

is performed via a serial digital control (which can accommo-

date “daisy chaining” of several devices) or via a parallel control

allowing updating of an individual output without reprogram-

ming the entire array.

PRODUCT DESCRIPTION

The AD8114/AD8115 are high speed 16 × 16 video crosspoint

switch matrices. They offer a –3 dB signal bandwidth greater

than 200 MHz and channel switch times of less than 50 ns with

1% settling. With –70 dB of crosstalk and –90 dB isolation (@

5 MHz), the AD8114/AD8115 are useful in many high speed

applications. The differential gain and differential phase of

better than 0.05% and 0.05° respectively, along with 0.1 dB

flatness out to 25 MHz while driving a 75 Ω back-terminated

load, make the AD8114/AD8115 ideal for all types of signal

switching.

The AD8114/AD8115 is packaged in 100-lead LQFP package

and is available over the extended industrial temperature range

of –40°C to +85°C.
