HD151TS302RP

www.DataSheet4U.com HD151TS302RP Spread Spectrum Clock for EMI Solution ADE-205-655A (Z) Preliminary Rev. 1 Sep. 2001 Description The HD151TS302 is a high-performance Spread Spectrum Clock modulator. It is suitable for low EMI solution. Features Supports 10 MHz to 60 MHz operation. (Designed for XIN = 24 MHz and 48 MHz) 1 copy of clock out with spread spectrum modulation @3.3 V 1 copy of reference clock @3.3 V Programmable spread spectrum modulation (–0.5%, –1.0%, –3.0% down spread modulation and spread spectrum disable mode.) SOP–8pin Pin to pin compatible with HD151TS301RP Key Specifications Supply voltages : VDD = 3.3 V±0.165 V Ta = 0 to 70°C operating range Clock output duty cycle = 50±5% Cycle to cycle jitter = ±250 ps typ.
