Product Description

Product Details
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 −98 dB isolation (at 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 a 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 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 accommodate daisy-chaining of several devices) or via a parallel control, allowing updating of an individual output without reprogramming the entire array.
The AD8114/AD8115 is packaged in a 100-lead LQFP and is available over the extended industrial temperature range of −40°C to +85°C.
Applications
Routing of high speed signals, including
– Video (NTSC, PAL, S, SECAM, YUV, RGB)
– Compressed video (MPEG, wavelet)
– 3-level digital video (HDB3)
– Data communications
– Telecommunications
### Features and Benefits
16 × 16 high speed nonblocking switch arrays: G = 1
Serial or parallel programming of switch array
Serial data out allows daisy-chaining of multiple 16 × 16 arrays to create larger switch arrays
High impedance output disable allows connection of
multiple devices without loading the output bus
For smaller arrays see the AD8108/AD8109 (8 × 8) or AD8110/AD8111 (16 × 8) switch arrays
Complete solution
Buffered inputs
Programmable high impedance outputs
16 output amplifiers (G = 1)
Drives 150 Ω loads
Excellent video performance
25 MHz, 0.1 dB gain flatness
0.05%/0.05° differential gain/differential phase error (RL = 150 Ω)
Excellent ac performance
−3 dB bandwidth: 225 MHz
Slew rate: 375 V/µs
Low power of 700 mW (2.75 mW per point)
Low all hostile crosstalk of −70 dB at 5 MHz
Reset pin allows disabling of all outputs (connected through a capacitor to ground provides power-on reset capability)
100-lead LQFP (14 mm × 14 mm)
