9ZXL1231AKLF

Overview

The Renesas 9ZXL1231AKLF is a high-performance, low-power zero-delay clock buffer featuring 12 differential outputs. It operates within a supply voltage range of 3.135 V to 3.465 V and supports maximum input frequencies up to 150 MHz. The device exhibits a maximum propagation delay of 4.5 ns and maintains a duty cycle of no more than 55%. Designed for surface mount applications, it is housed in a 64-pin VFQFPN package with dimensions of 9x9 mm. The component functions within an operating temperature range of 0°C to +70°C and draws a typical operating current of 110 mA.
