Description:The 87016I is a low skew, 1:16 LVCMOS/LVTTL Clock Generator and is a member of the HiPerClockS family of High Performance Clock Solutions. The device has 4 banks of 4 outputs and each bank can be independently selected for ÷1 or ÷2 frequency operation. Each bank also has its own power supply pins so that the banks can operate at the following different voltage levels: 3.3V, 2.5V, and 1.8V. The low impedance LVCMOS/LVTTL outputs are designed to drive 50? series or parallel terminated transmission lines. The
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 using an external overcurrent protection circuit, such as a fuse or a dedicated overcurrent protection IC, to prevent damage to the device. The datasheet provides guidelines for selecting the appropriate overcurrent protection component.
While the datasheet specifies an operating temperature range of -40°C to 125°C, Renesas recommends operating the device within a narrower range of -20°C to 85°C for optimal performance and reliability.
Renesas provides a troubleshooting guide in their application note (APL-AN-1202) which covers common issues with the I2C interface, such as bus contention, clock stretching, and data corruption, along with recommended solutions.
Renesas recommends a specific power-up sequence to ensure proper device initialization and to prevent damage. The recommended sequence is: VCC, then VDD, followed by the clock signal.
