詳細說明
The ICS502 LOCO™ is the most cost effective way to generate a high quality, high frequency clock output and a reference from a low 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. Features• Packaged as 8 pin SOIC or die• ICS’ lowest cost PLL clock plus reference• Zero ppm multiplication error• Easy to cascade with other 5xx series• Input crystal frequency of 5 - 27 MHz• Input clock frequency of 2 - 50 MHz• Output clock frequencies up to 160 MHz• Low jitter - 50 ps one sigma• Compatible with all popular CPUs• Duty cycle of 45/55 up to 160 MHz• Operating voltages of 3.0 to 5.5V• Industrial temperature version available• 25mA drive capability at TTL levels• Advanced, low power CMOS process

常見問題解答
What is ICS502?
The ICS502 is a high-performance clock generator IC manufactured by Integrated Device Technology (IDT). It is designed to generate various frequencies and timing signals for applications such as networking equipment, telecommunications, and industrial automation.
How Does ICS502 Work?
The ICS502 works by taking an input reference clock and using internal frequency dividers, phase-locked loops (PLLs), and output drivers to generate multiple synchronized clock outputs with precise frequencies and phases. It provides flexibility in generating clock signals tailored to specific system requirements.
How Many Pins does ICS502 have and What are the Functions of the Pinout Configuration?
The ICS502 is typically available in a 32-pin QFN (Quad Flat No-leads) package. The pinout configuration includes:
- XTAL/CLKIN: Crystal oscillator input or external clock input.
- REF_SEL: Reference clock selection pin.
- S0-S2, VDD, VDD_PLL: Configuration and power supply pins.
- OE: Output enable pin.
- CLK_OUTx: Multiple clock output pins (x represents different output channels).
- CLK_OUT_SEL: Output clock select pin.
- DRV0-DRV3: Output driver strength adjustment pins.
What are the Pros and Cons of ICS502?
Pros:
- High Performance: Provides precise and synchronized clock signals for complex systems.
- Multiple Outputs: Generates multiple clock signals to support various system components.
- Flexible Configuration: Allows for customization of output frequencies and phases.
- Integrated Features: Includes PLLs and dividers for versatile clock generation.
- Compact Package: Available in a space-saving QFN package for efficient board layout.
Cons:
