PLL N-COUNTER

The

N-COUNTER

(0x14, 0x16, Base + 0x18 = 1h) R/W

is a 21 bit control word that is

transmitted to the DBS9900 VXI Interface FPGA in one 16-bit and one 5-bit write. The software
driver writes to the control bits located in

0x18 = 1h

of the VXI FPGA. This register instructs the

FPGA that the next two register writes,

0x14

and

0x16

will be directed through a parallel to serial

shift register to the

N-COUNTER

. The control word

C[4:1]

, is concatenated to the end of the bit

string, and controls the register inside the PLL that is to be loaded upon completion of the serial
transfer. The software driver shall writes the MSB’s of the

N-COUNTER

BASE + 0x14

. The

five LSB’s are transmitted to

BASE + 0x16

The 21-bit serial shift register is loaded MSB first, via the data input on the rising edge of the
clock when the Latch Enable (

PLL_LE

) goes low. Loading is complete after 21 rising edges. The

internal register is latched on the rising edge of

PLL_LE

. The

N-COUNTER

divides the VCO

clock down to the Phase Detector comparison frequency (

Fpd

). The

N-COUNTER

is loaded

when the control bits

C[4:1]

are set to

. When the

N-COUNTER

is selected, 5-bits of the 21 bit,

shift register is transferred to a 5-bit latch which sets a 5-bit pulse swallow counter (

A-

COUNTER

A 13-bit latch transfers data to a 13-bit counter (

B-COUNTER

). Together, these counters act in

consort to give a division ratio from 24

≤

65,535, where 0

≤

7, 3

≤

8191 and

≤

The formula for this division ratio is:

N = [(P X B) + A]

where

P = 8

. When used with the JTOS-

200 the values for

will range from 2000

≤

4000. The VCO frequency can be calculated with

the following formula:

Fvco = Fref X [(P X B) + A] / R

The

N-COUNTER

should be initialized to the following state:

•

B[12:0] = 1F4h = 500d, A[3:0] = 0h.

200MHz / 50kHz = 4000 => N = [(P X B) + A] => P = 8, B = 500, A = 0.
