Type

Description

CLKIN0

I, DIF

True clock input.

CLKINb0

I, DIF

Complementary clock input.

VDDIN0

PWR

Power supply for clock input 0.

CLKIN1

I, DIF

True clock input.

CLKINb1

I, DIF

Complementary clock input.

VDDIN1

PWR

Power supply for clock input 1.

CLKSEL_tri

I, SE, PD,

Input to select differential input clock 0 or differential input clock 1. This input has an

internal pull-up and pull-down resistor to bias a floating pin to the mid-point.

0 = CLKIN0 selected for all outputs.

1 = CLKIN1 selected for all outputs.

M = CLKIN0 goes to bank 0 and CLKIN1 goes to bank 1.

VDDCLK_1

PWR

Power supply for clock output bank 1.

CLK5

O, DIF

True clock output.

CLKb5

O, DIF

Complementary clock output.

ZOUTSEL_tri

I, SE, PD,

Input to select differential output impedance.

0 = 85Ω, 1 = 100Ω, M = 34Ω

Note: This pin is bi-level on the RC19202 clock multiplexer with an internal pull-down,

which results in a default output impedance of 85Ω when left floating.

This pin is tri-level on the RC19302 with both internal pull-up and pull-down resistors.

On the RC19302, this results in a default output impedance of 34Ω when left floating.

This pin must be pulled down or pulled up to select an output impedance of 85Ω or 100Ω,

respectively.

OEb5

I, SE, PU,

PDT

Active low input for enabling output 5.

0 = Enable output, 1 = Disable output.

LOSb

O, OD,

PDT

Output indicating Loss of Input Signal. This pin is an open drain output and requires an

external pull up resistor for proper functionality. A low output on this pin indicates a loss of

signal on the input clock.

VDDA

PWR

Power supply for analog circuitry.

OEb2

I, SE, PU,

PDT

Active low input for enabling output 2.

0 = Enable output, 1 = Disable output.
