The LTC6905IS5-80#TRMPBF belongs to programmable timers and oscillators and finds wide application in a variety of fields. Its highly reliable timing and frequency-generation performance make it a popular choice among engineers.

The main application field of the LTC6905IS5-80#TRMPBF is to generate solutions for a range of pulse width modulation (PWM) control applications, including fan, motor and lighting control, as well as noise suppression in telecommunications switches and CCD drivers, to name a few. The oscillator operates froma high precision crystal and provides several output frequencies, which can be generated in any combination of clock and square wave outputs.

The LTC6905IS5-80#TRMPBF is a digitally programmable monolithic oscillator that employs a precise temperature compensated crystal oscillator core and a pair of high-drive complementary outputs to provide precise clock generation. Its topology includes a low noise, wide bandwidth Oscillator Core with an extremely low intrinsic jitter of 0.3ps that helps minimize the need for external components and requires only a few external resistors to set the frequency of operation. The maximum frequency of operation is 8MHz.

The device has a programmable "Slow Start" feature with a fixed time of 2ms, which enables it to start slowly to prevent stressing power supply voltages during power-up. The oscillator core can be powered up in either the disabled or enabled state. When the device is powered up in the enabled state, the output frequencies are enabled as soon as the Low Power supply is at 3V. However, when the device is powered up in the disabled state, the output frequencies will be enabled at the set "Slow start” time for the Manual Mode or after the LOCK/RELEASE pin is driven low to activate the Auto Mode.

The LTC6905IS5-80#TRMPBF also includes an adjustable slew-rate limiter that can be used to reduce the rate of change of the output waveform, which helps to reduce noise on the output. The slew-rate limit is adjustable from approximately 0.4V/µs to 250V/µs when driven from the PWM Timing Pin. The slew-rate limiter is disabled when the PWM Timing Pin is at low logic levels.

Overall, the LTC6905IS5-80#TRMPBF is an ideal solution for applications requiring precise clock generation, low noise, wide bandwidth and low power consumption. Its wide range of features and its compatibility with a variety of clock formats make it suitable for a variety of applications across many industries.
