MK1581-01GILF - Renesas Electronics
Description: The MK1581-01 provides synchronization and timing control for T1 and E1 based network access or multitrunk telecommunication systems. The device accepts an 8 kHz frame clock input and uses an on-chip VCXO to produce a synchronized low phase noise clock output. This monolithic IC, combined with an external inexpensive quartz crystal, can be used to replace a more costly hybrid VCXO retiming module. Through selection of external loop filter components values, the device can be tailored to meet the system's cl
