Description:The 85408I is a low skew, high performance 1-to-8 Differential-to-LVDS Clock Distribution Chip and a member of the family of High Performance Clock Solutions from IDT. The 85408I CLK, nCLK pair can accept most differential input levels and translates them to 3.3V LVDS output levels. Utilizing Low Voltage Differential Signaling (LVDS), the 85408I provides a low power, low noise, low skew, point-to-point solution for distributing LVDS clock signals. Guaranteed output and part-to-part skew specifications make
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, to ensure optimal thermal performance.
Renesas recommends a specific power sequencing scheme in their application note (APL-AN-1202) to ensure proper device operation and prevent latch-up. The sequence involves powering up the VCC, then the VDD, and finally the AVCC and AVDD.
Renesas provides guidelines for EMI and RFI mitigation in their application note (APL-AN-1203), including recommendations for PCB layout, component selection, and shielding to minimize electromagnetic interference and radio-frequency interference.
Renesas recommends several techniques to optimize the 85408BGILFT for low power consumption, including using the low-power mode, reducing clock frequency, and minimizing I/O pin toggling. Additionally, the device's power management features, such as the Power Management Controller (PMC), can be used to control power consumption.
The 85408BGILFT is manufactured according to Renesas' quality and reliability standards, which include compliance with industry standards such as AEC-Q100 and ISO/TS 16949. Additionally, the device is subjected to various environmental and reliability tests, including temperature, humidity, and vibration testing.
