Description:The 85320I is a LVCMOS / LVTTL-to-Differential 3.3V, 2.5V LVPECL translator. The 85320I has a single ended clock input. The single ended clock input accepts LVCMOS or LVTTL input levels and translates them to 3.3V or 2.5V LVPECL levels. The small outline 8-pin SOIC package makes this device ideal for applications where space, high performance and low power are important.
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.
Renesas recommends a specific power sequencing scheme in their application note (R01AN2732EU0100) to ensure proper device operation. The sequence involves powering up the VCC, VCCIO, and VREF pins in a specific order.
Renesas recommends using 0.1uF to 1uF decoupling capacitors with a voltage rating of 10V or higher, placed as close as possible to the power pins (VCC, VCCIO, and VREF) to minimize noise and ensure stable operation.
Renesas provides a JTAG interface specification in their datasheet, which includes information on signal levels, clock frequency, and protocol. Engineers can use this information to develop custom test fixtures or use third-party JTAG test equipment.
The thermal resistance values for the 85320AMILFT package are not explicitly stated in the datasheet. However, Renesas provides a thermal model in their application note (R01AN2732EU0100) which includes thermal resistance values for the package, allowing engineers to estimate junction temperatures and design for thermal management.
