www.DataSheet4U.com FUJITSU SEMICONDUCTOR DATA SHEET DS04-29122-1E Spread Spectrum Clock Generator MB88162 ■ DESCRIPTION MB88162 is a clock generator for EMI (Electro Magnetic Interference) reduction. The peak of unnecessary radiation noise (EMI) can be attenuated by making the oscillation frequency slightly modulate periodically with the internal modulator. ■ FEATURES Input frequency : 12 MHz to 28 MHz (Multiplied by 1), 20 MHz to 42 MHz (Multiplied by 4) Multiplication rate : 1, 4 Output frequency : 12 MHz to 28 MHz (Multiplied by 1), 80 MHz to 168 MHz (Multiplied by 4) Modulation rate : no modulation, ± 0.5%, ± 1.0%, ± 2.0%, − 1.0%, − 2.0%, − 4.0% (The terminal can be selected.) Equipped with oscillation circuit : Range of oscillation 12 MHz to 42 MHz Built-in oscillation stabilization capacitance : 4 pF (Typ) Modulation clock output Duty : 40% to 60% Modulation clock Cycle-Cycle Jitter : Less than 100 ps Low power consumption by CMOS process : 7.0 mA (24 MHz : no load, Typ-sample, Typ-condition) Power supply voltage : 2.7 V to 3.6 V (Multiplied by 1), 3.0 V to 3.6 V (Multiplied by 4) Operating temperature : − 40 °C to + 85 °C Package : BCC 18-pin ■ PACKAGE 18-pin plastic BCC (LCC-18P-M05) MB88162 ■ PIN ASSIGNMENT (TOP VIEW) NC NC NC NC S0 VSS SPRD OUT S1 15 14 13 12 11 10 16 17 18 1 2 NC 3 NC 4 NC 5 NC MB88162 9 8 7 6 OE XOUT XIN VDD MLTP ■ PIN DESCRIPTION Pin no. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 Pin name S1 NC NC NC NC MLTP...
