DESCRIPTION

I

Resets the scrambler when asserted.

-

Most positive power supply connection for analog circuits.

-

Most negative power supply connection for analog circuits.

I

Differential VCO current setting resistor that sets the VCO frequency.

-

Most negative power supply connection (substrate).

I

TTL level loop bandwidth control that adjusts the PLL bandwidth to optimize for lowest

jitter. If the pin is set to ground the loop bandwidth is BWMIN. If the pin is left floating, the

loop bandwidth is approximately 3 BWMIN, if the pin is tied to VCC the loop bandwidth is

approximately10 BWMIN

I

Differential loop filter pins to optimize loop transfer performance at low loop bandwidths

(NC if not used).

I

Sync detect disable. Logic high disables sync detection. Logic low allows 8 bit operation

by mapping 000-003 to 000 and 3FC-3FF to 3FF.
