Description:The 85322I is a Dual LVCMOS / LVTTL-to- Differential 2.5V / 3.3V LVPECL translator. The 85322I has selectable single ended clock inputs. The single ended clock input accepts LVCMOS or LVTTL input levels and translate them to 2.5V / 3.3V 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 (APL-AN-1201) which includes thermal design considerations, such as thermal vias, copper pours, and component placement.
Renesas recommends a specific power sequencing scheme in their datasheet, which involves powering up the VCC and VDD pins in a specific order. Additionally, they provide a power sequencing diagram in their application note (APL-AN-1202).
Renesas recommends using 0.1uF to 1uF decoupling capacitors with a voltage rating of 10V to 16V, placed as close as possible to the VCC and VDD pins. The exact value and type of capacitor may vary depending on the specific application and PCB design.
Renesas provides a troubleshooting guide in their application note (APL-AN-1203) which covers common issues, such as power-on reset, clocking, and communication errors. Additionally, they recommend using oscilloscopes and logic analyzers to debug the system.
The recommended operating temperature range for the 85322AMILF is -40°C to 125°C, as specified in the datasheet. However, it's essential to consider the specific application and environmental conditions to ensure reliable operation.
