Additionally, further relaxation was obtained in routing the signals by introducing circuits that delay the clock signal
with respect to address, command under program control.
In order to employ CMOS technology to enable high-speed operation in the signal-generating circuitry and to realize output of 40Gbps output waveforms at qualities equivalent to those generated by compound semiconductors, not only does the operational speeds of data-transmitting circuits need to be accelerated, but the clock signals
- which are provided to circuits to determine their operational timing, must operate at 20GHz with low noise and sufficient amplitude.
Free-running clock (FRC): A free-running clock is used to improve integrity of the clock signal
by removing inter-symbol interference (ISI).
With the new method, an on-chip clock jitter formation circuit is used to intentionally introduce jitter and periodically switch between clock signals
with long and short oscillating frequencies -- without changing oscillating frequency of the clock signal
introduced from outside the LSI.
NASDAQ: SLAB), a leader in high-performance, analog-intensive, mixed-signal ICs, today announced the industry's most frequency-flexible timing IC solution for networking and telecommunications applications that require jitter attenuation for clock signals
without clock multiplication.
These devices are phase locked-loop (PLL) based buffers that can take an input clock signal
and distribute it as multiple clock signals
with zero input-output propagation delay and very low skew between the outputs.
The XTR series also boasts the only JTAG interface that can accurately measure clock signal
Fine Programming Granularity, Effective Clock Signal
Remedy, with Fast "Days-to-Samples" Hand Designers Speedy Time to Market
8 /PRNewswire-FirstCall/ -- NEC Corporation (NEC) and NEC Electronics Corporation (NEC Electronics) today announced the development and verification of technology that achieves the world's most accurate on-chip measurement of clock signal
CMOS clock generator creates a stable high frequency clock signal
with minimal power dissipation, remains operational over an extreme temperature range, and does not require external components
All buffers have PCIe specification-compliant differential host clock signal
level (HCSL) outputs.
Some systems distribute a clock signal
from board to board, so if the main system clock fails, the local (backup) clock will be switched over to continue the operation.
