Description:The 8735BI-21 is a highly versatile 1:1 Differential-to-3.3V LVPECL clock generator. The CLK, nCLK pair can accept most standard differential input levels. The 8735BI-21 has a fully integrated PLL and can be configured as zero delay buffer, multiplier or divider, and has an output frequency range of 31.25MHz to 700MHz. The referencedivider, feedback divider and output divider are each programmable, thereby allowing for the following output-to-input frequency ratios: 8:1, 4:1, 2:1, 1:1, 1:2, 1:4, 1:8. The ex
Renesas provides a recommended PCB layout guide in their application note (R01AN3804EU0100) 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 (R01AN3804EU0100) 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 VCC, VCCIO, and VREF pins.
The 8735BKI-21LFT has multiple low-power modes, including Sleep, Deep Sleep, and Power-Down modes. Configuration involves setting specific registers and using the Power Management Interface (PMI) to control the device's power consumption.
The 8735BKI-21LFT has an operating temperature range of -40°C to +85°C, but it's essential to follow the thermal design guidelines to ensure reliable operation within this range.
