PI6C3420A
27 MHz Spread Spectrum
Clock Synthesizer
Description
The PI6C3420A is spread spectrum clock synthesizer targeted
for video and graphics applications. The primary purpose of
the spread spectrum is to minimize EMI emissions. This device
generates two 27.000 MHz outputs: a 27.000 MHz down spread
spectrum output and a 27.000 MHz non-spread spectrum output.
The PI6C3420A down spread range is from –1% to –1.75% when
output frequency is at 27 MHz. Spread spectrums are selectable
through external pins.
Typically, the PI6C3420A uses a 14.318 MHz input crystal or
frequency source to generate a 27 MHz clock output. Users
can also get the adequate output clock setting from 15.1 MHz to
46.2 MHz by tuning the input frequency which can be set from 8 MHz
to 24.5 MHz; the frequency multiplication factor is 1.886X.
The PI6C3420A is housed in a lead-free and green, SOT-23, 6-pin
SOTiny package.
The PI6C3420A belongs to Pericom's clock and timing products.
