813N252BKI-09LF Description

The 813N252BKI-09LF is a high-performance clock generator from Renesas Electronics Corporation’s FemtoClock® series, designed for precision timing applications in advanced electronic systems. This surface-mount IC operates within a 3.135V to 3.465V supply range and supports a maximum frequency of 312.5MHz, making it suitable for high-speed communication and networking equipment. It features a 2:2 input-to-output ratio with HCSL, LVDS, LVHSTL, LVPECL, and SSTL input compatibility, delivering LVPECL outputs for low-jitter signal integrity. The device integrates a PLL with bypass capability and offers divider functionality (no multiplier), ensuring flexible clock distribution. Packaged in a 32VFQFPN tray, it is classified as Not For New Designs, indicating its maturity in legacy systems.

813N252BKI-09LF Features

• Low-jitter LVPECL outputs for high-speed signal integrity.
• Wide input compatibility (HCSL, LVDS, LVHSTL, LVPECL, SSTL) for versatile system integration.
• PLL with bypass mode enables precise clock synthesis or direct signal pass-through.
• 3.3V operation (3.135V–3.465V) with 312.5MHz max frequency for demanding applications.
• Differential I/O (Yes/Yes) reduces noise susceptibility in high-frequency environments.
• ROHS3 Compliant and REACH Unaffected, meeting environmental regulations.
• MSL 3 (168 hours) moisture sensitivity for controlled handling.
