1:1 DIFFERENTIAL-TO-LVDS ZERO DELAY
CLOCK GENERATOR
ICS8745B-21
IDT / ICS LVDS ZERO DELAY CLOCK GENERATOR
1
ICS8745BM-21REV. C APRIL 17, 2007
Description
The ICS8745B-21 is a highly versatile 1:1 LVDS
Clock Generator and a member of the HiPerClockS
f family of High Performance Clock Solutions from
IDT. The ICS8745B-21 has a fully integrated PLL
and can be configured as zero delay buffer,
multiplier or divider, and has an output frequency range of
31.25MHz to 700MHz. The Reference Divider, Feedback Divider
and Output Divider are each programmable, thereby allowing for
the following output-to-input frequency ratios: 8:1, 4:1, 2:1, 1:1,
1:2, 1:4, 1:8. The external feedback allows the device to achieve
“zero delay” between the input clock and the output clock. The
PLL_SEL pin can be used to bypass the PLL for system test and
debug purposes. In bypass mode, the reference clock is routed
around the PLL and into the internal output dividers.
Features
One differential LVDS output designed to meet
or exceed the requirements of ANSI TIA/EIA-644
One differential feedback output pair
Differential CLK, CLK input pair
CLKx, CLKx pair can accept the following differential
input levels: LVPECL, LVDS, LVHSTL, HCSL, SSTL
Output frequency range: 31.25MHz to 700MHz
Input frequency range: 31.25MHz to 700MHz
VCO range: 250MHz to 700MHz
External feedback for “zero delay” clock regeneration
with configurable frequencies
Programmable dividers allow for the following output-to-input
frequency ratios: 8:1, 4:1, 2:1, 1:1, 1:2, 1:4, 1:8
Cycle-to-cycle jitter: 30ps (maximum)
Output skew: 35ps (maximum)
Static phase offset: 25ps ± 125ps
Full 3.3V supply voltage
0°C to 70°C ambient operating temperature
Available in both standard (RoHS 5) and lead-free (RoHS 6)
