Package
The LTC
®
6905-XXX series are precision, fixed frequency
silicon oscillators designed to minimize board space while
maximizing accuracy and ease of use.
Programmed at the factory to a fixed frequency, the
LTC6905-XXX series of parts need no external trim com-
ponents. An internal three-state divider allows for division
of the master clock by 1, 2 or 4, providing 3 frequencies
(for each device).
The LTC6905-XXX series operate with a single 2.7V to
5.5V power supply and provide a rail-to-rail, 50% duty
cycle, square wave output. The OE pin will disable the
output when brought low and synchronously enable the
output when brought high, avoiding pulse slivers.
The four products of the LTC6905-XXX family are:
LTC6905-133: f
OSC
= 133MHz, 66.7MHz, 33.3MHz
LTC6905-100: f
OSC
= 100MHz, 50MHz, 25MHz
LTC6905-96: f
OSC
= 96MHz, 48MHz, 24MHz
LTC6905-80: f
OSC
= 80MHz, 40MHz, 20MHz
The LTC6905-XXX series of parts provides a factory trim
option to modify the divider ratios from 1, 2, 4 to 8, 16, 32.
A second trim option allows for additional master clock
frequencies. For the alternate divider ratios and unlisted
frequencies, contact LTC marketing.
