LOCOTM PLL CLOCK MULTIPLIER Description
The IDT5V40501 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 160 MHz. 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 or guaranteed. For applications which require defined input to output skew, use the ICS570B. The IDT5V40501 is an enhanced performance version of the ICS501 and ICS501B and should be used for all new designs.

External Components
Decoupling Capacitor
As with any high-performance mixed-signal IC, the IDT5V40501 must be isolated from system power supply noise to perform optimally. A decoupling capacitor of 0.01F must be connected between VDD and the GND. It must be connected close to the IDT5V40501 to minimize lead inductance. No external power supply filtering is required for the IDT5V40501.
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 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. 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 33 terminating resistor can be used next to the CLK pin for trace lengths over one inch.
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the IDT5V40501. These ratings, which are standard values for IDT 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.
