PCK9456
PCK9456 is 2.5 V and 3.3 V LVCMOS clock fan-out buffer manufactured by NXP Semiconductors.
description
The PCK9456 is a 2.5 V and 3.3 V patible 1 : 10 clock distribution buffer designed for low voltage mid-range to high-performance telemunications, networking and puting applications. Both 3.3 V, 2.5 V and dual supply voltages are supported for mixed voltage applications. The PCK9456 offers 10 low-skew outputs and a differential LVPECL clock input. The outputs are configurable and support 1 : 1 and 1 : 2 output to input frequency ratios. The PCK9456 is specified for the extended temperature range of
- 40 °C to +85 °C.
