ASM3P4201A

Multi-Output Custom Clock Generator

Features

clock generator. The five high frequency Clock outputs

are generated using an inexpensive 20MHz Crystal or

external reference clock. The accuracy of the 20MHz

Input Clock should be within ±50ppm. The output clocks

consist of a low EMI spread spectrum clock and other

non-spread clocks. Three Select bits choose the

combination of Output Clock Frequency. Refer to the

Output Frequency Selection Table for the values. Output

clocks can be disabled using the STBY pin. The device

operates from a Supply Voltage of 3.3V±0.3V with a

tolerable ripple voltage of 50mV . The device is available

in a 20 pin TSSOP JEDEC package.

• Generates five clock outputs from an inexpensive

20MHz crystal or external reference clock.

• Output Frequencies are selectable through select bits

• Generates an EMI optimized clock signal at the output.

• ±1.5% (Typ) Centre Spread for Spread Spectrum Clock

Outputs

• Operates with a 3.3V ± 0.3V Supply Voltage

• Output Clocks disable feature using STBY pin

• Available in 20-pin TSSOP.
