Unused

Input

Do not connect.

XTAL1, XTAL2

Crystal oscillator interface. XTAL1 is the input. XTAL2 is the output.

Parallel load input. Determines when data present at M8:M0 is loaded into

M divider, and when data present at N1:N0 sets the N output divide value.

LVCMOS / LVTTL interface levels.

nP_LOAD

Input

Pullup

Clocks the serial data present at S_DATA input into the shift register on the

rising edge of S_CLOCK. LVCMOS / LVTTL interface levels.

Shift register serial input. Data sampled on the rising edge of S_CLOCK.

LVCMOS / LVTTL interface levels.

Controls transition of data from shift register into the M divider.

LVCMOS / LVTTL interface levels.

S_LOAD

M0, M1, M2

M3, M4, M5

M6, M7, M8

M divider inputs. Data latched on LOW-to-HIGH transition of nP_LOAD input.

LVCMOS / LVTTL interface levels.

Input

Pullup

Determines N output divider value as defined in Table 3C Function Table.

LVCMOS / LVTTL interface levels.

N0, N1

Test output which is used in the serial mode of operation.

LVCMOS / LVTTL interface levels.

Differential output for the synthesizer. 3.3V LVPECL interface levels.

TEST

Output

nFOUT, FOUT

NOTE: Pullup and Pulldown refer to internal input resistors. See Table 2, Pin Characteristics, for typical values.
