1. Basic Product Information

1.1 Product Series

Multiphase Oscillator with Spread Spectrum Frequency Modulation

1.2 Manufacturer

Linear Technology Corporation (LTC; LTC, LT are registered trademarks)

1.3 Core Function

Provides 2-, 3-, or 4-phase clock outputs with optional spread spectrum frequency modulation (SSFM) to improve EMC performance. Frequency and spread percentage are set by external resistors, offering high precision and low power consumption.

1.4 Key Features

Output Phases: Selectable 2-phase, 3-phase, or 4-phase configurations.
Frequency Range: 5kHz to 20MHz (adjustable via one external resistor RSET).
SSFM Function: Optional frequency spreading (set by one external resistor RMOD) to reduce peak electromagnetic radiation.
Precision Performance: Frequency error ≤1.5% (max, 5kHz–10MHz, TA=25°C), ±40ppm/°C temperature stability.
Low Power Consumption: Typical supply current 400µA (VS=3V, 1MHz frequency).
Fast Start-Up: 50µs to 1.5ms start-up time.
Output Driver: 100Ω CMOS output driver, compatible with 5kΩ and/or 10pF loads.
Supply Voltage: Single 2.7V to 5.5V supply.
Compliance: Pb-Free (indicated by #PBF suffix).
