Notes on Operation
1. Clock synthesizer (PLL)
The CXB1585N has a PLL-based clock recovery circuit for recovering the clock from the serial data. This clock
recovery circuit requires an external loop filter and an external resistor which determines the VCO center
frequency. The external part circuit and recommended constant values are shown in the figure below. The
parasitic capacitance attached to the IC pins (Pins 12, 13 and 14) which are used to connect external parts
should be kept as small as possible in order to obtain the good PLL characteristics. In addition, capacitor C1
should have a small temperature coefficient to reduce the temperature dependence of the VCO oscillation
frequency.
