CTS100LVEL11NG

Clock Buffers, Drivers Overview

The CTS100LVEL11NG is a differential 1:2 fan-out buffer manufactured by CTS-Frequency Controls, designed for high-performance AC applications. It operates with LVPECL inputs and outputs within a 3V to 5V supply range. The device features a 265ps typical propagation delay and 5ps output skew. Packaged in an 8-MLP (2x2) surface-mount format, it includes internal input pull-down resistors and clamping circuitry to maintain stability under open input conditions. The component supports an operating temperature range of -40°C to +85°C.

Clock Buffers, Drivers FAQ

What happens if the differential inputs are left open?

The device employs clamping circuitry that causes the Q outputs to go LOW if the inputs are left open.

Does the CTS100LVEL11 have internal termination?

No, the datasheet specifies that each output must be terminated through a 50 Ω resistor to VCC - 2V for proper operation.

Is this component suitable for new designs?

No, the datasheet explicitly states that the CTS100LVEL11 is not recommended for new designs.
