DESCRIPTIONS

The K²951C is in a 16-pin SSOP (0.150 inch)

package and is functional pin compatible to

K²941C.

The KRYPTON K²950G DAA (Data Access

Arrangement) chipset consists of K²951C,

K²952C and K²934L. The KRYPTON

K²950GU DAA (Data Access Arrangement)

chipset consists of K²951C, K²952C and

K²935U, which is an UL-recognized

component. The silicon chipsets, with their

associated external components, provide all

the necessary line monitoring, filtering,

isolation, protection and signal conversion

functions for the connection of high speed

analog modem devices (V.34/33.6Kbps and

V.90/56Kbps) to the public switched

telephone network using only +5V/+3.3V

power supply (20mW active, 50uW standby)

for modem applications. The chipset is

designed for isolation from 1KVrms for

FCC/DOC and 1.5KVrms for UL safety

requirements.

The Differential Transmit Input Buffer

receives the input signals from the modem

chipset's transmit output pins. The K²951C

differential Transmit input pins have an

internal DC bias at ½ of the VCC (+5V or

3.3V) and 65KOhm input impedance.

The Differential Receive Output Buffers

output signals to the modem chipset's receive

pins. With the DC bias at ½ of VCC (5V or

3.3V), the buffers can have a maximum load

(lowest resistance) of 10KW at RCV+ or

RCV- pins (Pin 4 or Pin 5) to an AC ground.

The Ring Detect Circuit will detect and

output active low ringing signal at DOUT pin

during K²951C power down mode. The

output active low frequency is equal to the

actual ring signal frequency on the line.

The KRYPTON K²950G/K²950GU is an

SSOP (0.150 inch) packaged chipset.

The OFFHOOK and CALLER ID Control

Input Circuit senses the control levels from

the input pins OFFHK\ and CLID\ (active

low). This circuit then transfers these control

signals through the K²934L or K²935U to the

K²952C, which controls the external

transistors to activate the HOOK switch and

the CALLER ID switches. (See Functional

Diagram, Figure 1.)

FUNCTIONAL DESCRIPTION

K²951C

The K²951C is a 16-pin integrated circuit,

which interfaces to a modem chipset,

Modem/Voice Codec or any other electronic

system. It contains

The Power Down Circuit is controlled by

the OFFHK\ and CLID\ control input pins

(Pins 14 and 11). When the OFFHOOK and

CALLER ID both are not active (both inputs

high), the K²951C is in a power-down mode

with only 50uW power consumption. When

either control input is active (input low), the

K²951C exits the Power-Down Mode and

requires 20mW power to operate. The circuit

will be at test mode if both OFFHOOK and

CALLER ID are active simultaneously (both

inputs low).

The K²952C is in a 28-pin SSOP (0.150 inch)

package and is functional pin compatible to

K²942C.

The K²951C has an On-chip 700KHZ

Oscillator. The RSET pin (Pin 8) requires a

100 kW/1% resistor. This resistor sets the

operating frequency of this oscillator, as well

as internal current biasing levels within the

integrated circuit.

The DC Voltage Termination and Line

Power Reference Block regulates telephone

line current to supply the K²952C reference

voltage. The circuit is designed to provide a

termination over a loop current range from

10mA to 120mA during the OFFHOOK

mode. The voltage termination falls within

the worst case current requirements of FCC

Part 68 and DOC CS-03, and DC resistance

is less than 300 ohm at 20mA loop current,

and is less than 150 ohm at 120mA. By

changing the external 39W resistor value, the

K²952 DC V/I termination will change. The

line power reference block will regulate

certain loop current from the phone line and

generate 2.7VDC to 7.6VDC at VDR pin

(PIN 20) with 10mA to 120mA loop current

supply. The 59kW external resistor sets the

K²952C internal biasing current and must be

within 1% tolerance. The TER1 pin and

TER2 pin control the external NPN transistor

Q3 to meet the line DC V/I termination

requirements.

An Isolation Input/Output Interface

Circuit transfers all signals through the

isolation barrier constituted by the isolation

capacitors K²934L or K²935U, using

KRYPTON Patented Technology.

K²952C

The K²952C is powered from the telephone

line. It receives the OFFHOOK or CALLER

ID control signals from the K²951C, which

then enables the K²952C to activate the

external transistors which allows it to receive

power from the line (different amount of

power for CALLER ID than for OFFHOOK).

The K²952C then transfers all necessary

analog signals from/to the telephone line (TIP

and RING) through the isolation capacitors

(/K²934L or K²935U) to/from the K²951C. It

contains

The 2 to 4 Wire Converter Hybrid has a

trans-hybrid loss of typically 30dBm when

connected as shown in Functional Diagram

Figure 1, when the telephone line has a 600W

AC termination impedance. For minimum

echo on the line, Pin LINE (Pin 21) connects

to an AC termination network RT (604 ohm).

impedance values matching between the

phone line AC impedance.

driver, transferring the signal through the

K²934L or K²935U to the K²951C. The

Caller ID signal then is presented at the

RCV+/RCV- output pins (Pin 4 and Pin 5) of

the K²951C.

The Transmit and Receive Drivers interface

to a 2 to 4 wire converter and hybrid circuit

for optimizing the impedance match. When

the K²951C OFFHK\ input is low (active),

the transmit driver outputs a signal to the

phone line. The maximum signal swing

driving to the line could be 3Vpp from 10mA

to 120mA loop current supply. The receive

driver receives a 2 to 4 wire converted signal

from the phone line. The maximum receive

signal from the line could be 2Vpp from

10mA to 120mA loop current supply.

The Ring Signal Receive Block will receive

ring signal from the line and then pass the

1MHZ 5Vpp clock signal to K²951C via

K²934L or K²935U isolation capacitors. The

K²951C will regulate the clock signal and

then output true ring frequency with active

low voltage at K²951C pin DOUT. During

the ringing, the K²952C will take few uA AC

ring current to power up internal oscillator. If

proper ring impedance termination is

required, then external 0.47uF/250V

capacitor and 7.5K resistor must be installed

cross the tip and ring.

The Transmit Gain and Trans-Hybrid Loss

are both set by an external resistor, nominally

84.5W. The value of 84.5W is set at

The Isolation Input/Output Interface

Circuit connects to the isolation capacitors

K²934L or K²935U to transfer the signals

through the isolation barrier using

maximum trans-hybrid loss for a 600W AC

line impedance termination. Changing the

value will change both the trans-hybrid loss

and the transmit gain.

KRYPTON Patented Technology.

The OFFHOOK and Caller ID Control

Circuits receive the control signals from the

K²951C via the isolation capacitors K²934L

or K²935U, convert and output the

appropriate control signals to external

OFFHOOK and Caller ID circuits. The

KRYPTON K²950G/ K²950GU chipset has

been designed in such a way that by using

K²934L or K²935U as the isolation barriers

for all signals, the external OFFHOOK

switch circuit and Caller ID circuit can be

built using low cost surface mount (SOT-23)

300V transistors.

K²934L and K²935U

The K²950G chipset includes six K²934L

isolation capacitors. This isolation barrier

withstands the minimum 1000VAC or

1500VDC required by FCC Part 68 and DOC

CS-03 standards. The K²950GU chipset

includes six K²935U isolation capacitors. The

K²935U has received UL component

recognition to UL1950, and can withstand

1500VAC/2500VDC. The K²934L or

K²935U isolation capacitors connect between

the K²951C and K²952C Isolation

input/output interface circuits to transfer

signals across the isolation barrier using

KRYPTON Patented Technology.

The Caller ID Receive Buffer Circuit will

be active when the K²951C CLID\ pin (Pin

11) input is low. This circuit will draw less

than 1mA of current from the telephone line

and pass the Caller ID signal to the Receive
