RC193xx Datasheet

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.

VDDCLK_0

PWR

Power supply for clock output bank 0.

VDDA

PWR

Power supply for core multiplexer circuitry.

CLK3

O, DIF

True clock output.

CLKb3

O, DIF

Complementary clock output.

OEb3

I, SE, PU,

PDT

Active low input for enabling output 3.

0 = Enable output, 1 = Disable output.

OEb2

I, SE, PU,

PDT

Active low input for enabling output 2.

0 = Enable output, 1 = Disable output.

SADR_tri1

I, SE, PD,

SMBus address bit. This is a tri-level input that works in conjunction with other SADR

pins, if present, to decode SMBus Addresses. See the SMBus Address Selection

(RC19308) table and refer to the tri-level input thresholds in the electrical tables.

CLK2

O, DIF

True clock output.

CLKb2

O, DIF

Complementary clock output.

VDDCLK_0

PWR

Power supply for clock output bank 0.

CLK1

O, DIF

True clock output.

CLKb1

O, DIF

Complementary clock output.

(RC19308A)

SLEWRATE_SEL

I, SE, PU,

PDT

Input to select default output slew rate.

0 = Slow slew rate.

1 = Fast slew rate.

(RC19308A0

01)

AMPLITUDE_SEL

I, SE, PD,

PDT

Input to select output amplitude. The values are programmable with defaults listed below.

See AMP_CTRL_DEF for default amplitude and AMP_CTRL_ALT for alternate

amplitude.

0 = Select Default Amplitude (800mV),

1 = Select Alternate Amplitude (900mV)

OEb1

I, SE, PU,

PDT

Active low input for enabling output 1.

0 = Enable output, 1 = Disable output.

OEb0

I, SE, PU,

PDT

Active low input for enabling output 0.

0 = Enable output, 1 = Disable output.

CLK0

O, DIF

True clock output.

CLKb0

O, DIF

Complementary clock output.

VDDCLK_0

PWR

Power supply for clock output bank 0.

GNDSUB

GND

Ground pin for substrate.

EPAD

PWR

Ground.
