8 GHZ FRACTIONAL SYNTHESIZER

Table 2. Pin Descriptions

Pin Number

Function

Description

SCK

CMOS Input: Serial port clock

CMOS Input: Serial port data

SDI

DVDD

VDDIO

LD_SDO

TRIG

Power Supply for digital - Nominal 3.3 V MAX 25 mA, f

dependent

Power Supply for Digital IO - 3.3 V, 8 mA MAX (only when driving LD_SDO)

CMOS Output: General Purpose Output - Lock Detect, Serial Data Out, others, Selectable

CMOS Input : External Trigger pin.

N/C

No Connect

VCCPS

Power Supply for RF Divider, Nominal 3.3 V 35 mA MAX

No Connect

N/C

VCOIP

Differential RF Inputs. Normally AC Coupled, 2 V DC bias generated internally. For Single Ended

operation, RFN must be AC coupled to the ground plane, typically 100 pF ceramic. DC Bias of 2.3 V is

generated internally

VCOIN

VCCHF

VDDLS

VPPCPA

Power Supply for RF Buffer, Nominal 3.3 V, 6 mA MAX

Power Supply for PFD to CP Level Shifters, Nominal 5 V, 5 mA MAX, f

Power Supply for charge pump, Nominal 5 V, 10 mA MAX

Charge pump output

dependent.

AVDD

Power supply for analog bias generation, Nominal 3.3 V, 2 mA MAX

External bypass decoupling for precision bias circuits, 1.920 V +/-2 mV

BIAS

NOTE: BIAS ref voltage cannot drive an external load. Must be measured with 10 GΩ meter such as

Agilent 34410A, normal 10 MΩ DVM will read erroneously.

RVDD

N/C

Power Supply for Reference path, Nominal 3.3 V. 15 mA MAX reference dependent

No Connect

XREFP

Reference Input. DC bias is generated internally. Normally AC coupled externally.

Power Supply for phase detector. Nominally 3.3 V. Decoupling for this supply is critical. 5 mA MAX, f

dependent

VDDPD

N/C

CEN

SEN

No Connect

CMOS Input: Hardware Chip Enable

CMOS Input: Serial port latch enable
