ICS840-77 datasheet, synthesizer equivalent, Integrated Circuit Systems

ICS840-77 synthesizer equivalent, crystal-to lvcmos/lvttl frequency synthesizer.

Features and benefits

* One LVCMOS/LVTTL output, 15Ω output impedence
* Crystal oscillator interface designed for 19.44MHz, 18pF parallel resonant crystal
* Output frequency: 77.76.

Application

not requiring the use of the crystal oscillator input, both XTAL_IN and XTAL_OUT can be left floating. Though not requir.

Description

The ICS840-77 is a SONET Oscillator Replacement and a member of the HiPerClocks TM HiPerClockS™ family of high performance devices from ICS. The ICS840-77 uses a 19.44MHz crystal to synthesize 77.76MHz. The ICS840-77 has excellent jitter performance..
