342MPLF - Renesas Electronics

Description: The 342 is a low cost, dual-output, field programmable clock synthesizer. The 342 can generate two output frequencies from 250 kHz to 200 MHz, using up to two independently configurable PLLs. The outputs may employ Spread Spectrum techniques to reduce system electro-magnetic interference (EMI). Using ICS' VersaClockTM software to configure the PLL and output, the 342 contains a One-Time Programmable (OTP) ROM to allow field programmability. Programming features include 2 selectable configuration registers.

342MPLF Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (APL-AN-1201) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
  • Renesas recommends using an external overcurrent protection circuit, such as a fuse or a dedicated overcurrent protection IC, to prevent damage to the device. The datasheet provides guidelines for selecting the appropriate protection components.
  • According to Renesas, the maximum allowed voltage on the VCC pin during power-up and power-down sequences is 4.5V. Exceeding this voltage may cause damage to the device.
  • Renesas provides EMC design guidelines in their application note (APL-AN-1202) which includes recommendations for PCB layout, component selection, and shielding to minimize electromagnetic interference.
  • The recommended operating temperature range for the 342MPLF is -40°C to 125°C. However, Renesas recommends derating the device's performance at temperatures above 85°C to ensure reliable operation.
