DESCRIPTION:
loop (PLL) clock driver. It has four banks of configurable outputs. The
IDT5V9351 uses a differential PECL reference input and an external feedback
input. These features allow the IDT5V9351 to be used as a zero delay, low
skew fan-out buffer. REF_SEL allows selection between PECL input or TCLK,
a CMOS clock driver input.
so, the IDT5V9351 will be in clock buffer mode. Any clock applied to TCLK will
be divided down to four output banks.
be clocked in both phase and frequency to FBIN. PECL clock is activated by
setting REF_SEL to low.
The IDT5V9351 is a high performance, zero delay, low skew, phase-lock
If PLL_EN is set to low and REF_SEL to high, it will bypass the PLL. By doing
When PLL_EN is set high, PLL is enabled. Any clock applied to TCLK will
