GENERAL DESCRIPTION
The AD9300 is a monolithic high speed video signal multiplexer
usable in a wide variety of applications.
Its four channels of video input signals can be randomly
switched at megahertz rates to the single output. In addition,
multiple devices can be configured in either parallel or cascade
arrangements to form switch matrices. This flexibility in using
the AD9300 is possible because the output of the device is in a
high-impedance state when the chip is not enabled; when the
chip is enabled, the unit acts as a buffer with a high input im-
pedance and low output impedance.
An advanced bipolar process provides fast, wideband switching
capabilities while maintaining crosstalk rejection of 72 dB at
10 MHz. Full power bandwidth is a minimum 27 MHz. The
device can be operated from ±10 V to ±15 V power supplies.
PIN DESIGNATIONS
DIP
LCC and PLCC
The AD9300K is available in a 16-pin ceramic DIP and a
20-pin PLCC and is designed to operate over the commercial
temperature range of 0°C to +70°C. The AD9300TQ is a
hermetic 16-pin ceramic DIP for military temperature range
(–55°C to +125°C) applications. This part is also available pro-
cessed to MIL-STD-883. The AD9300 is available in a 20-pin
LCC as the model AD9300TE, which operates over a tempera-
ture range of –55°C to +125°C.
The AD9300 Video Multiplexer is available in versions compli-
ant with MIL-STD-883. Refer to the Analog Devices Military
Products Databook or current AD9300/883B data sheet for de-
tailed specifications.
