the

PCS5I9653A

running at either 4x or 8x of the reference clock frequency.

The PCS5I9653A is guaranteed to lock in a low power PLL

mode in the high frequency range (VCO_SEL = 0) down to

PLL = 145 MHz or Fref = 36.25MHz.

The PCS5I9653A has a differential LVPECL reference

input long with an external feedback input. The device is

ideal for use as a zero delay, low skew fanout buffer. The

device performance has been tuned and optimized for zero

delay performance. The PLL_EN and BYPASS controls

select the PLL bypass configuration for test and diagnosis.

In this configuration, the selected input reference clock is

bypassing the PLL and routed either to the output dividers

or directly to the outputs. The PLL bypass configurations

are

fully

static

and

the

minimum

clock

frequency

specification and all other PLL characteristics do not apply.

The outputs can be disabled (high-impedance) and the

device reset by asserting the MR/OE pin. Asserting MR/OE

also causes the PLL to loose lock due to missing feedback

signal presence at FB_IN. Deasserting MR/OE will enable

the outputs and close the phase locked loop, enabling the

PLL to recover to normal operation. The PCS5I9653A is

fully 3.3V compatible and requires no external loop filter

components. The inputs (except PCLK) accept LVCMOS

except signals while the outputs provide LVCMOS

compatible levels with the capability to drive terminated

50Ω transmission lines. For series terminated transmission

lines, each of the PCS5I9653A outputs can drive one or

two traces giving the devices an effective fanout of 1:16.

The device is packaged in a 7x7 mm2 32-lead LQFP &

TQFP Packages.

Functional Description

The PCS5I9653A utilizes PLL technology to frequency lock

its outputs onto an input reference clock. Normal operation

of the PCS5I9653A requires the connection of the QFB

output to the feedback input to close the PLL feedback path

(external feedback). With the PLL locked, the output

frequency is equal to the reference frequency of the device

and VCO_SEL selects the operating frequency range of 25

to 62.5MHz or 50 to 125MHz. The two available post-PLL

dividers selected by VCO_SEL (divide-by-4 or divide-by-8)

and the reference clock frequency determine the VCO

frequency. Both must be selected to match the VCO

frequency range. The internal VCO of the PCS5I9653A is
