SP5669 Overview
The SP5669 is a single chip frequency synthesiser designed for tuning systems up to 2.7GHz and offers step size patible with DTT offset requirements. The RF preamplifier drives a divide by two prescaler which can be disabled for applications up to 2GHz, allowing direct interfacing with the programmable divider so enabling a step size equal to the parison frequency. For applications up to 2.7GHz the divide by two is...
