Description:The Intersil HS-26CLV32RH, HS-26CLV32EH are radiation hardened 3. 3V quad differential line receivers designed for digital data transmission over balanced lines, in low voltage, RS-422 protocol applications. Radiation hardened CMOS processing assures low power consumption, High-Speed, and reliable operation in the most severe radiation environments. The HS-26CLV32RH, HS-26CLV32EH have an input sensitivity of 200mV (typical) over a common-mode input voltage range of -4V to +7V. The receivers are also equippe
Renesas provides a recommended PCB layout guide in their application note (APN) documents, which can be found on their website. The guide includes thermal vias, heat sink recommendations, and PCB layer stack-up suggestions to ensure optimal thermal performance.
Renesas recommends using an external POR circuit with a voltage supervisor IC, such as the RP108 series, to ensure a reliable power-on reset. The POR circuit should be designed to monitor the VCC voltage and assert a reset signal to the HS9-26CLV32RH-Q when the voltage is below a certain threshold.
Renesas provides EMC and EMI guidelines in their application notes and design guides. Key considerations include using a solid ground plane, minimizing signal loop areas, and using shielding and filtering techniques to reduce EMI emissions and improve immunity.
Renesas recommends following their thermal design guidelines, including using a heat sink, thermal interface material, and ensuring good airflow around the device. Additionally, the device should be operated within its specified temperature range, and the system should be designed to mitigate thermal gradients and hotspots.
The HS9-26CLV32RH-Q requires a clock signal with a specific frequency, duty cycle, and jitter tolerance. Renesas recommends using a clock signal with a frequency of 26 MHz, a duty cycle of 40-60%, and a jitter tolerance of ±100 ppm. The clock signal should also be properly terminated and filtered to minimize noise and reflections.
