HSTL Low Voltage Differential
Clock
The MPC998 is a low voltage 3.3V, HSTL differential clock synthesizer.
The clock is designed to support single and multiple processor systems
requiring HSTL differential inputs. The MPC998 supports two differential
HSTL output pairs that may be operated from 520 MHz to 840 MHz.
Features:
2 clock outputs: (PCLK0 and PCLK1), each fully selectable
Fully integrated PLL
Output frequencies from 520 MHz to 840 MHz
HSTL outputs
HSTL and LVPECL reference clocks
32 lead LQFP packaging
The fully integrated Phase Locked Loop multiplies the HSTL_CLK in-
put or the PECL_CLK input frequency to the desired processor clock fre-
quency.
The PLL may be bypassed for test purposes such that the PCLK out-
puts are fed directly from the HSTL_CLK or PECL_CLK input.
All outputs are HSTL. The PCLK outputs are capable of driving 25
to
ground with at least 600mV p-p signals. The EXTFB_OUT is capable of
driving 50
ground with at least a 600 mV p-p signal. For on-chip power
reduction, the outputs are powered from 1.8V external supply. For zero
delay applications the buffer can operate with either external or internal
feedback.
