ICS663
ICS663 is PLL BUILDING BLOCK manufactured by Renesas.
PLL BUILDING BLOCK
Description
The ICS663 is a low cost Phase-Locked Loop (PLL) designed for clock synthesis and synchronization. Included on the chip are the phase detector, charge pump, Voltage Controlled Oscillator (VCO) and an output buffer. Through the use of external reference and VCO dividers (implemented with the ICS674-01, for example), the user can easily configure the device to lock to a wide variety of input frequencies.
The phase detector and VCO functions of the device can also be used independently. This enables the configuration of other PLL circuits. For example, the ICS663 phase detector can be used to control a VCXO circuit such as the MK3754.
