DESCRIPTION:

The FCT388915T uses phase-lock loop technology to lock the fre-

quency and phase of outputs to the input reference clock. It provides low

skew clock distribution for high performance PCs and workstations. One

of the outputs is fed back to the PLL at the FEEDBACK input resulting

in essentially zero delay across the device. The PLL consists of the

phase/frequency detector, charge pump, loop

ﬁ

lter and VCO. The VCO

is designed for a 2Q operating frequency range of 40MHz to f2Q Max.

The FCT388915T provides 8 outputs, the

output is inverted from

the Q outputs. The 2Q runs at twice the Q frequency and Q/2 runs at

half the Q frequency.

The FREQ_SEL control provides an additional ÷ 2 option in the

output path. PLL _EN allows bypassing of the PLL, which is useful in

static test modes. When PLL_EN is low, SYNC input may be used as

a test clock. In this test mode, the input frequency is not limited to the

speciﬁed range and the polarity of outputs is complementary to that in

normal operation (PLL_EN = 1). The LOCK output attains logic HIGH

when the PLL is in steady-state phase and frequency lock. When OE/

RST

is low, all the outputs are put in high impedance state and registers

at Q,

and Q/2 outputs are reset.

The FCT388915T requires one external loop

ﬁ

lter component as

recommended in Figure 3.
