LVCMOS Clock Generator
ICS870919I-01
DATA SHEET
General Description
The ICS870919I-01 is an LVCMOS clock generator that uses an
internal phase lock loop (PLL) for frequency multiplication and to lock
the low-skew outputs to the selected reference clock. The device
offers eight outputs. The PLL loop filter is completely internal and
does not require external components. Several output configurations
of the PLL feedback and a divide-by-2 (controlled by FREQ_SEL)
allow applications to optimize frequency generation over a wide
range of input reference frequencies. The PLL can also be disabled
by the PLL_EN control signal to allow for low frequency or DC testing.
The LOCK output asserts to indicate when phase-lock has been
achieved. The ICS870919I-01 device is a member of the family of
high performance clock solutions from IDT.
