..
- Down-spread:
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 Peri's clock and timing products. For other frequencies, features
, functions or input/output not specified, please contact Peri for information.
- Four Down-Spread options:
- 1% to
- 1.75%
- 14.318 MHz input (crystal or external reference)
- Single 3.3V Power Supply
- Packaging (Pb-Free and Green):
- SOTiny™ 6-pin SOT-23 (T)
