Product Overview
LTC®6908 is an easy-to-use precision oscillator. The oscillator frequency is programmed by a single external resistor (RSET) and spread spectrum frequency modulation (SSFM) can be activated for improved electromagnetic compatibility (EMC) performance. The LTC6908 operates with a single 2.7V to 5.5V supply and provides rail-to-rail, 50% duty cycle square wave outputs. A single resistor from 10K to 2M is used to select an oscillator frequency from 50KHz to 10MHz (5V supply). The oscillator can be easily programmed using the simple formula: fOUT =10MHz*10K/RSET. The LTC6908's SSFM capability modulates the output frequency by a pseudorandom noise (PRN) signal to decrease the peak electromagnetic radiation level and improve EMC performance. The amount of frequency spreading is fixed at ±10% of the centre frequency. Applications include switching power supply clock reference, portable and battery-powered equipment, precision programmable oscillator and charge pump driver.
- Complementary outputs (0°/180°)
- ±10% frequency spreading, 400µA supply current typical (V+ = 5V, 50KHz)
- Frequency error <=1.5% max (TA = 25°C, V+ = 3V), ±40ppm/°C temperature stability
- Fast start-up time: 260µs typical (1MHz), outputs muted until stable
- Operates from a single 2.7V to 5.5V supply
- Duty cycle of 50% typical (no modulation, 250KHz <= fOUT <= 1MHz)
- 6-lead (2mm × 3mm) plastic DFN package, -40°C to 85°C temperature range
