LOCOPLL CLOCK MULTIPLIER Description
ICS501B LOCOis most cost effective generate high-quality clock output from lower frequency crystal clock input. name LOCO stands Cost Oscillator, designed replace crystal oscillators most electronic systems. Using Phase-Locked Loop (PLL) techniques, device uses standard fundamental mode, inexpensive crystal produce output clocks MHz. Stored chip's ability generate nine different multiplication factors, allowing chip output many common frequencies (see table page device also output enable which tri-states clock output when taken low. This product intended clock generation. output jitter (variation output period), input output skew jitter defined guaranteed. applications which require defined input output skew, ICS570B.
ICS501B Features
Packaged SOIC Available (lead) free package IDT's lowest cost clock Zero multiplication error Output clock frequencies Extremely jitter (one sigma) Compatible with popular CPUs Duty cycle 45/55 Nine selectable frequencies Operating voltage Tri-state output board level testing drive capability levels Ideal oscillator replacement Industrial temperature version available Advanced, low-power CMOS process

External Components
Decoupling Capacitor
with high-performance mixed-signal ICS501B must isolated from system power supply noise perform optimally. decoupling capacitor 0.01µF must connected between GND. must connected close ICS501B minimize lead inductance. external power supply filtering required ICS501B.
parallel resonant, fundamental mode crystal should used. device crystal connections should include pads small capacitors from ground from ground. These capacitors used adjust stray capacitance board match nominally required crystal load capacitance. Because load capacitance only increased this trimming process, important keep stray capacitance minimum using very short traces (and vias) between crystal device. Crystal capacitors, needed, must connected from each pins ground. value these crystal caps should equal pF)*2. this equation, crystal load capacitance Example: crystal with load capacitance, each crystal capacitor would [(16-12)
