I/O

DESCRIPTION

FIN-A,

FIN-B

4

5

I

Frequency signal inputs for PFD. The reference frequency signal (fREF-IN) and the VCO output signal

through the external counter device are applied to these terminals. When the LPF design is the lag-lead filter

(passive filter and noninverting), f(REF-IN) is input to FIN-A, and the VCO output signal is to FIN-B.

LOGIC GND

7

GND terminal for the internal logic circuit

LOGIC VDD

1

Power supply terminal for the internal logic circuit. This power supply terminal separates from VCO VDD to

reduce cross-coupling between supplies.

PFD INHIBIT

9

I

PFD INHIBIT (power-down) control signal input terminal

PFD OUT

6

O

PFD output terminal. When PFD INHIBIT is high, PFD OUT is in the high-impedance state.

RBIAS

13

I

Bias resistor (RBIAS) terminal. Connect a resistor between VCO GND and this terminal to supply bias to

internal VCO circuit. TLC2934 bias resistor connection is different from TLC2932 and TLC2933, where bias

resistor RBIAS is connected to VCO VDD.

SELECT

2

I

1/2 divider select terminal. L=through output, H=1/2 output.

TEST

8

Test terminal. Use for production test. Tie to GND when in normal use.

VCO GND

11

GND terminal for internal VCO

VCO OUT

3

O

VCO output terminal. When VCO INHIBIT = high, VCO OUT is low.

VCO INHIBIT

10

I

VCO INHIBIT (power-down) control signal input terminal

VCO IN

12

I

VCO control voltage input terminal. Normally, The external LPF is connected to this terminal.

VCO VDD

14

Power supply terminal for the internal VCO circuit. This power supply terminal should be separate from

LOGIC VDD to reduce cross-coupling between supplies.

† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not

implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values are with respect to network ground terminal.

2. For operation above 25

°C free–air temperature, derate linearly at the rate of 5.6 mW/°C
