LVCMOS Clock Generator
ICS870931I-01
General Description
The ICS870931I-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 reference clock. The device offers six
outputs. The PLL loop filter is completely internal and
does not require external components. Several combinations 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
ICS870931I-01 device is a member of the HiperClocks family of high
performance clock solutions from IDT.
