840002AGI-01LF - Renesas Electronics

Description: The 840002I-01 is a two output LVCMOS/LVTTL Synthesizer optimized to generate Ethernet reference clock frequencies. Using a 25MHz 18pF parallel resonant crystal, the following frequencies can be generated based on the two frequency select pins (F_SEL[1:0]): 156.25MHz, 125MHz, and 62.5MHz. The 840002I-01 uses IDT's 3RD generation low phase noise VCO technology and can achieve 1ps or lower typical random rms phase jitter, easily meeting Ethernet jitter requirements. The 840002I-01 is packaged in a small 16-pi

840002AGI-01LF Frequently Asked Questions (FAQs)

  • Renesas provides a recommended PCB layout guide in their application note (R01AN3804EU0100) which includes thermal design considerations, such as thermal vias, copper pours, and component placement, to ensure optimal thermal performance.
  • Renesas recommends a specific power sequencing scheme to ensure proper device operation. This involves powering up the VCC and VCCIO pins simultaneously, followed by the VREF pin. A detailed power sequencing diagram is available in the datasheet.
  • Although the datasheet specifies the recommended operating conditions, it's essential to note that the maximum allowed voltage on the input pins is VCC + 0.3V to prevent damage to the device.
  • Renesas recommends implementing ESD protection measures, such as using ESD diodes or TVS diodes, to protect the device from electrostatic discharge. A detailed ESD protection circuit is available in the application note (R01AN3804EU0100).
  • To ensure proper device operation, Renesas recommends maintaining a clock signal integrity with a minimum rise time of 1ns, a maximum clock skew of 100ps, and a clock duty cycle of 40% to 60%.
