Pin Definitions
Signal Name	IO				Description
REF	I	Reference frequency input. This input supplies the frequency and timing against which all functional
		variations are measured.
FB	I	PLL feedback input (typically connected to one of the eight outputs).
FS	I	Three level frequency range select. See Table 1.
1F0, 1F1	I	Three level function select inputs for output pair 1 (1Q0, 1Q1). See Table 2.
2F0, 2F1	I	Three level function select inputs for output pair 2 (2Q0, 2Q1). See Table 2.
3F0, 3F1	I	Three level function select inputs for output pair 3 (3Q0, 3Q1). See Table 2.
4F0, 4F1	I	Three level function select inputs for output pair 4 (4Q0, 4Q1). See Table 2.
TEST	I	Three level select. See “Test Mode” on page 4 under the “Block Diagram Description” on page 3.
1Q0, 1Q1	O	Output pair 1. See Table 2.
2Q0, 2Q1	O	Output pair 2. See Table 2.
3Q0, 3Q1	O	Output pair 3. See Table 2.
4Q0, 4Q1	O	Output pair 4. See Table 2.
VCCN	PWR	Power supply for output drivers.
VCCQ	PWR	Power supply for internal circuitry.
GND	PWR	Ground.
