Description:The 87004 is a highly versatile 1:4 Differential-to-LVCMOS/LVTTL Clock Generator and a member of the HiPerClockS® family of High Performance Clock Solutions from IDT. The 87004 has two selectable clock inputs. The CLK0, nCLK0 and CLK1, nCLK1 pairs can accept most standard differential input levels. Internal bias on the nCLK0 and nCLK1 inputs allows the CLK0 and CLK1 inputs to accept LVCMOS/LVTTL. The 87004 has a fully integrated PLL and can be configured as zero delay buffer, multiplier or divider and has a
Renesas provides a recommended PCB layout guide in their application note (R01AN2732EU0100) 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 in their application note (R01AN2732EU0100) to ensure proper device operation. The sequence involves powering up the VCC, then the VDD, and finally the AVCC and DVCC supplies.
Renesas recommends implementing EMI and ESD protection measures, such as using EMI filters, shielding, and ESD protection devices, to ensure reliable operation and meet regulatory requirements. Refer to the Renesas EMI and ESD design guides for more information.
To optimize the 87004AGLF for low power consumption, use the device's power-saving modes, such as the Sleep and Stop modes, and optimize the clock frequency and voltage settings. Additionally, consider using a low-power oscillator and minimizing the number of active peripherals.
The 87004AGLF's ADC has limitations on its conversion speed, resolution, and input range. The ADC can operate at a maximum conversion speed of 1.5 Mbps, has a resolution of 12 bits, and an input range of 0 to VCC. Ensure that your application requirements are within these limitations.
