CM5391L GEN-M9K-20
Flexible Clock Generators MIPS Based Systems
PMC-Sierra's CM5391L clock generator industry's only device tailored drive clocking inputs PMC-Sierra's leading line processors using MIPS architectures, such RM9000x1 RM9000x2 PMC-Sierra's CM5391L clock generator superior price, size, power performance other discrete solutions. Output frequency pin-selectable support frequencies MHz, including common computing frequencies 50.00 MHz, 66.67 MHz, 83.33 MHz, 100.00 MHz, 125.00 MHz, 133.33 MHz, 166.67 MHz, 200.00 MHz.
SPREAD SPECTRUM
Provides optional spread spectrum phase modulation control. Triangular spread spectrum modulation algorithm pin-selectable common modulation frequencies up-spread down-spread ranges.
CHARACTERISTICS
output electrical options supported. (Other output electrical options available. Contact your authorized PMC-Sierra sales representative.) SYSCLK1: Differential LVDScompatible SYSCLK2, SYSCLK3: Single-ended LVTTL Nominal duty cycle with 125ps max. cycle-to-cycle phase jitter. Three copies output clock generated, controlled "output enable" inputs. Maximum output-to-output skew between SYSCLK SYSCLK3.
