High Frequency System Clock Generator
The ICS9177 is a multiple output clock generator ideal for
high speed processor system applications. A single high-
speed internal VCO is utilized to derive up to four simultaneous
clock output frequencies. This enables output clock skew
matching and the minimization of clock jitter. The internal
VCO operates up to 350 MHz providing edge skew matched
output clocks.
One differential PECL (Positive ECL) output pair provides a
high speed processor clock. 12 TTL clock outputs are also
provided for other system functions, such as bus clocks. Input
selection pins are used to select the TTL output clock
frequencies.
For information about ICS9177 customization optics, please
contact ICS.
Provides output frequencies up to 175 Mhz
Internal VCO is divided into four skew-matched output
frequencies (Out A, B, C, D)
External clock feedback provides input to output skew
matching
Differential PECL clock output pair provided for high
speed output (Out A)
12 TTL clock outputs (for Out B, C, D)
Single 5 volt power supply voltage
Internal loop filters
52-pin QFP package
Pin Configuration
