Renesas Electronics Corporation Clock/Timing - Clock Generators, PLLs, Frequency Synthesizers ICS722MLFT

The ICS722MLFT is a low-cost, low-jitter Voltage Controlled Crystal Oscillator (VCXO) designed for applications requiring a frequency range of 16.2 MHz to 28 MHz. It operates at a supply voltage of 3.3 V and features an on-chip VCXO that allows for frequency adjustment via an external control voltage input (VIN) ranging from 0 to 3.3 V. The device utilizes an inexpensive external pullable crystal, which can be selected based on specific parameters to ensure optimal performance. The ICS722MLFT is packaged in an 8-pin SOIC format and is compliant with RoHS standards. It offers a pull range of 230 ppm and has a drive capability of 12 mA at TTL levels. The device is suitable for applications in multimedia clock synthesis and can replace more expensive discrete VCXO modules. Proper operation requires minimal external components, including a decoupling capacitor and potentially series termination resistors for longer PCB traces. The recommended crystal parameters include an initial accuracy of ±20 ppm and a load capacitance of 14 pF.
