ICS511MI

DATASHEET ICS511 LOCO™ PLL CLOCK MULTIPLIER Description Features The ICS511 LOCOTM is the most cost effective way to generate a high quality, high frequency clock output from a lower frequency crystal or clock input. The name LOCO stands for Low Cost Oscillator, as it is designed to replace crystal oscillators in most electronic systems. Using Phase-Locked Loop (PLL) techniques, the device uses a standard fundamental mode, inexpensive crystal to produce output clocks up to 200 MHz. • Packaged as 8-pin SOIC or die • Available in Pb (lead) free package • Upgrade of popular ICS501 with: • • • • • • • • • • • • Stored in the chip’s ROM is the ability to generate nine different multiplication factors, allowing one chip to output many common frequencies (see table on page 2). The device also has an output enable pin which tri-states the clock output when the OE pin is taken low. This product is intended for clock generation. It has low output jitter (variation in the output period), but input to output skew and jitter are not defined nor guaranteed. For applications which require defined input to output skew, use the ICS570B. - changed multiplier table - faster operating frequencies - output duty cycle at VDD/2 Zero ppm multiplication error Input crystal frequency of 5 - 27 MHz Input clock frequency of 2 - 50 MHz Output clock frequencies up to 200 MHz Extremely low jitter of 25 ps (one sigma) Compatible with all popular CPUs Duty cycle of 45/55 up to 200 MHz Mask option for nine selectable frequencies Operating voltage of 3.3 V or 5 V Tri-state output for board level testing Industrial temperature version available Advanced, low power CMOS process NOTE: EOL for non-green parts to occur on 5/13/10 per PDN U-09-01 Block Diagram VDD S1:0 2 PLL Clock Multiplier Circuitry and ROM X1/ICLK Crystal or Clock input Crystal Oscillator CLK X2 Optional crystal capacitors GND IDT™ / ICS™ LOCO™ PLL CLOCK MULTIPLIER 1 OE ICS511 REV J 092209 ICS511 LOCO™ PLL CLOCK MULTIPLIER CLOCK MULTIPLIER Pin Assignment Clock Output Table S1 S0 CLK 0 0 4X input X1/ I CLK 1 8 X2 0 M 5.333X input VDD 2 7 OE 0 1 5X input GND 3 6 S0 M 0 2.5X input M M 2X input M 1 3.333X input 1 0 6X input 1 M 3X input 1 1 8X input S1 5 4 CLK 8 Pi n ( 150 mi l ) SOI C 0 = connect directly to ground 1 = connect directly to VDD M = leave unconnected (floating) Common Output Frequency Examples (MHz) Output 20 24 30 32 33.33 37.5 40 48 50 60 64 Input 10 12 10 16 16.66 15 10 12 20 10 16 Selection (S1, S0) M, M M, M 1, M M, M M, M M, 0 0, 0 0, 0 M, 0 1, 0 0, 0 Output 66.66 72 75 80 83.33 90 100 120 125 133.3 150 20 12 25 10 25 15 20 15 25 25 25 M, 1 1, 0 1, M 1, 1 M, 1 1, 0 0, 1 1, 1 0, 1 0, M 1, 0 Input Selection (S1, S0) Pin Descriptions Pin Number Pin Name Pin Type 1 XI/ICLK Input Crystal connection or clock input. 2 VDD Power Connect to +3.3 V or +5 V. 3 GND Power Connect to ground. 4 S1 Tri-level Iinput 5 CLK Output IDT™ / ICS™ LOCO™ PLL CLOCK MULTIPLIER Pin Description Select 1 for output clock.

External Components Decoupling Capacitor stray capacitance of the board to match the nominally required crystal load capacitance. Because load capacitance can only be increased in this trimming process, it is important to keep stray capacitance to a minimum by using very short PCB traces (and no vias) between the crystal and device. Crystal capacitors, if needed, must be connected from each of the pins X1 and X2 to ground. As with any high-performance mixed-signal IC, the ICS511 must be isolated from system power supply noise to perform optimally. A decoupling capacitor of 0.01µF must be connected between VDD and the GND. It must be connected close to the ICS511 to minimize lead inductance. No external power supply filtering is required for the ICS511. The value (in pF) of these crystal caps should equal (CL -12 pF)*2. In this equation, CL= crystal load capacitance in pF. Example: For a crystal with a 16 pF load capacitance, each crystal capacitor would be 8 pF [(16-12) x 2] = 8. Series Termination Resistor A 33Ω terminating resistor can be used next to the CLK pin for trace lengths over one inch. Crystal Load Capacitors The total on-chip capacitance is approximately 12 pF. A parallel resonant, fundamental mode crystal should be used. The device crystal connections should include pads for small capacitors from X1 to ground and from X2 to ground. These capacitors are used to adjust the IDT™ / ICS™ LOCO™ PLL CLOCK MULTIPLIER 3 ICS511 REV J 092209 ICS511 LOCO™ PLL CLOCK MULTIPLIER CLOCK MULTIPLIER Absolute Maximum Ratings Stresses above the ratings listed below can cause permanent damage to the ICS511. These ratings, which are standard values for ICS commercially rated parts, are stress ratings only. Functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can affect product reliability. Electrical parameters are guaranteed only over the recommended operating temperature range.
