MT8960/61/62/63/64/65/66/67
Functional Description
Figure 1 shows the functional block diagram of the
MT8960-67. These devices provide the conversion
interface between the voiceband analog signals of a
telephone subscriber loop and the digital signals
required in a digital PCM (pulse code modulation)
switching system. Analog (voiceband) signals in the
transmit path enter the chip at VX, are sampled at
8kHz, and the samples quantized and assigned 8-bit
digital values defined by logarithmic PCM encoding
laws. Analog signals in the receive path leave the
chip at V R after reconstruction from digital 8-bit
words.
Separate switched capacitor filter sections are used
for bandlimiting prior to digital encoding in the
transmit path and after digital decoding in the receive
path. All filter clocks are derived from the 2.048 MHz
master clock input, C2i. Chip size is minimized by
the use of common circuitry performing the A to D
and D to A conversion. A successive approximation
technique is used with capacitor arrays to define the
16 steps and 8 chords in the signal conversion
process. Eight-bit PCM encoded digital data enters
and leaves the chip serially on DSTi and DSTo pins,
respectively.
Transmit Path
Analog signals at the input (Vx) are firstly
bandlimited to 508 kHz by an RC lowpass filter
section. This performs the necessary anti-aliasing
for the following first-order sampled data lowpass
pre-filter which is clocked at 512 kHz. This further
bandlimits the signal to 124 kHz before a fifth-order
elliptic lowpass filter, clocked at 128 kHz, provides
the 3.4 kHz bandwidth required by the encoder
section. A 50/60 Hz third-order highpass notch filter
clocked at 8 kHz completes the transmit filter path.
Accumulated DC offset is cancelled in this last
section by a switched-capacitor auto-zero loop which
integrates the sign bit of the encoded PCM word, fed
back from the codec and injects this voltage level
into the non-inverting input of the comparator. An
integrating capacitor (of value between 0.1 and 1 µF)
must be externally connected from this point (ANUL)
to the Analog Ground (GNDA).
The absolute gain of the transmit filter (nominally 0
dB at 1 kHz) can be adjusted from 0 dB to 7 dB in 1
dB steps by means of three binary controlled gain
pads.
The resulting bandpass characteristics with the limits
shown in Figure 10 meet the CCITT and AT&T
recommended specifications. Typical atttenuations
6-22
ISO2-CMOS
are 30 dB for 0-60 Hz and 35 dB for 4.6 kHz and
above.
The filter output signal is an 8 kHz staircase
waveform which is fed into the codec capacitor array,
or alternatively, into an external capacitive load of
250 pF when the chip is in the test mode. The digital
encoder generates an eight-bit digital word
representation of the 8 kHz sampled analog signal.
The first bit of serial data stream is bit 7 (MSB) and
represents the sign of the analog signal. Bits 4-6
represent the chord which contains the analog
sample value. Bits 0-3 represent the step value of
the analog sample within the selected chord. The
MT8960-63 provide a sign plus magnitude PCM
output code format. The MT8964/66 PCM output
code conforms to the AT &T D3 specification, i.e.,
true sign bit and inverted magnitude bits. The
MT8965/67 PCM output code conforms to the CCITT
specifications with alternate digit inversion (even bits
inverted). See Figs. 3 and 4 for the digital output
code corresponding to the analog voltage, VIN, at VX
input.
The eight-bit digital word is output at DSTo at a
nominal rate of 2.048 MHz, via the output buffer as
the first 8-bits of the 125 µs sampling frame.
Receive Path
An eight-bit PCM encoded digital word is received on
DSTi input once during the 125 µs period and is
loaded into the input register. A charge proportional
to the received PCM word appears on the capacitor
array and an 8 kHz sample and hold circuit
integrates this charge and holds it for the rest of the
sampling period.
The receive (D/A) filter provides interpolation filtering
on the 8 kHz sample and hold signal from the codec.
The filter consists of a 3.4 kHz lowpass fifth-order
elliptic section clocked at 128 kHz and performs
bandlimiting and smoothing of the 8 kHz "staircase"
waveform. In addition, sinx/x gain correction is
applied to the signal to compensate for the
attenuation of higher frequencies caused by the
capacitive sample and hold circuit. The absolute
gain of the receive filter can be adjusted from 0 dB to
-7 dB in 1 dB steps by means of three binary
controlled gain pads.
The resulting lowpass
characteristics, with the limits shown in Figure 11,
meet the CCITT and AT & T recommended
specifications.
Typical attenuation at 4.6 kHz and above is 30 dB.
The filter is followed by a buffer amplifier which
will drive 5V peak/peak into a 10k ohm load, suitable
for driving electronic 2-4 wire circuits.
ISO2-CMOS
V Ref
An external voltage must be supplied to the V Ref pin
which provides the reference voltage for the digital
encoding and decoding of the analog signal. For
V Ref = 2.5V, the digital encode decision value for
overload (maximum analog signal detect level) is
equal to an analog input V IN = 2.415V (µ-Law
version) or 2.5V (A-Law version) and is equivalent to
a signal level of 3.17 dBm0 or 3.14 dBm0
respectively, at the codec.
The analog output voltage from the decoder at V R is
defined as:

V Ref is a high impedance input with a varying
capacitive load of up to 40 pF.
The recommended reference voltage for the MT8960
series of codecs is 2.5V ±0.5%. The output voltage
from the reference source should have a maximum
temperature coefficient of 100 ppm/C°. This voltage
should have a total regulation tolerance of ±0.5%
both for changes in the input voltage and output
loading of the voltage reference source. A voltage
reference circuit capable of meeting these
specifications is shown in Figure 5. Analog Devices

driving a large number of codecs due to the high
Normal

precautions should be taken in PCB layout design to
minimize noise coupling to this pin. A 0.1 µF
capacitor connected from V Ref to ground and located
as close as possible to the codec is recommended to
minimize noise entering through V Ref. This capacitor
should have good high frequency characteristics.
Timing
The codec operates in a synchronous manner (see
Figure 9a). The codec is activated on the first
positive edge of C2i after F1i has gone low. The
digital output at DSTo (which is a three-state output
driver) will then change from a high impedance state
to the sign bit of the encoded PCM word to be
output. This will remain valid until the next positive
edge, when the next most significant bit will be
output.
On the first negative clock edge (after F1i signal has
been internally synchronized and CA is at GNDD or
VEE) the logic signal present at DSTi will be clocked
into the input shift register as the sign bit of the
incoming PCM word.
The eight-bit word is thus input at DSTi on negative
edges of C2i and output at DSTo on positive edges
of C2i.
F1i must return to a high level after the eighth
clock pulse causing DSTo to enter high impedance
and preventing further input data to DSTi. F1i will
continue to be sampled on every positive edge of
C2i. (Note: F1i may subsequently be taken low
during the same sampling frame to enable entry of
serial data into CSTi. This occurs usually mid-frame,
in conjunction with CA=V DD, in order to enter an 8-bit
control word into Register B. In this case, PCM input
and output are inhibited by CA at VDD.)

Internally the codec will then perform a decode cycle
on the newly input PCM word. The sampled and
held analog signal thus decoded will be updated 25
µs from the start of the cycle. After this the analog
input from the filter is sampled for 18 µs, after which
digital conversion takes place during the remaining
82 µs of the sampling cycle.
Since a single clock frequency of 2.048 MHz is
required, all digital data is input and output at this
rate. DSTo, therefore, assumes a high impedance
state for all but 3.9 µs of the 125 µs frame. Similarly,
DSTi input data is valid for only 3.9 µs.
Digital Control Functions
CSTi is a digital input (levels GNDD to VDD) which is
used to control the function of the filter/codec. It
operates in three different modes depending on the
logic levels applied to the Control Address input
(CA) and chip enable input (F1i) (see Table 1).
Mode 2
CA= -5V (VEE); CSTi receives an eight-bit control
word
CSTi accepts a serial data stream synchronously
with DSTi (i.e., it accepts an eight-bit serial word in a
3.9 µs timeslot, updated every 125 µs, and is
specified
identically
to
DSTi
for
timing
considerations).
This eight-bit control word is
entered into Control Register A and enables
programming of the following functions: transmit and
receive gain, powerdown, loopback. Register B is
reset to zero and the SD outputs assume their
inactive state. Test modes cannot be entered.
Mode 3
CA=0V (GNDD); CSTi receives an eight-bit control
word
As in Mode 2, the control word enters Register A and
the aforementioned functions are controlled. In this
mode, however, Register B is not reset, thus not
affecting the states of the SD outputs.
Mode 1
CA=-5V (V EE); CSTi=0V (GNDD)
The filter/codec is in normal operation with nominal
transmit and receive gain of 0dB. The SD outputs
are in their active states and the test modes cannot
be entered.
CA=+5V (VDD); CSTi receives an 8-bit control word
In this case the control word is transferred into
Register B. Register A is unaffected. The input and
output of PCM data is inhibited.
CA = -5V (VEE); CSTi = +5V (VDD)
A state of powerdown is forced upon the chip
whereby DSTo becomes high impedance, V R is
connected to GNDA and all analog sections have
power removed.

Note: For Modes 1 and 2, F1i must be at logic low
for one period of 3.9 µs, in each 125 µs cycle, when
PCM data is being input and output, and the control
word at CSTi enters Register A. For Mode 3, F1i
must be at a logic low for two periods of 3.9 µs, in
each 125 µs cycle. In the first period, CA must be at
GNDD or VEE, and in the second period CA must be
high (VDD).

Control Registers A, B
The contents of these registers control the filter/
codec functions as described in Tables 2 and 3.
Bit 7 of the registers is the MSB and is defined as the
first bit of the serial data stream input (corresponding
to the sign bit of the PCM word).
By enabling Register B with valid data (eight-bit
control word input to CSTi when F1i=GNDD and CA=
VCC) the chip testing mode can be entered. Bits 6
and 7 (most sign bits) define states for testing the
transmit filter, receive filter and the codec function.
The input in each case is V X input and the output in
each case is VR output. (See Table 3 for details.)
Loopback
Loopback of the filter/codec is controlled by the
control word entered into Register A. Bits 6 and 7
(most sign bits) provide either a digital or analog
loopback condition. Digital loopback is defined as
follows:
• PCM input data at DSTi is latched into the PCM
input register and the output of this register is
connected to the input of the 3-state PCM
output register.
•
The digital input to the PCM digital-to-analog
decoder is disconnected, forced to zero (0).
•
The output of the PCM encoder is disabled and
thus the encoded data is lost. The PCM output
at DSTo is determined by the PCM input data.
Analog loopback is defined as follows:
• PCM input data is latched, decoded and filtered
as normal but not output at V R.
Table 2. Control States - Register A
•
Analog output buffer at V R has its input shorted
to GNDA and disconnected from the receive
filter output.
•
Analog input at V X is disconnected from the
transmit filter input.
•
The receive filter output is connected to the
transmit filter input. Thus the decode signal is
fed back through the receive path and encoded
in the normal way. The analog output buffer at
V R is not tested by this configuration.
In both cases of loopback,
and DSTo is the output.
DSTi is the input

Logic Control Outputs SD0-5
These outputs are directly controlled by the logic
states of bits 0-5 in Register B. A logic low (GNDD)
in Register B causes the SD outputs to assume an
inactive state. A logic high (V DD) in Register B
causes the SD outputs to assume an active state
(see Table 3). SD0-2 switch between GNDD and VDD
and may be used to control external logic or
transistor circuitry, for example, that employed on the
line card for performing such functions as relay drive
for application of ringing to line, message waiting
indication, etc.
SD3-5 are used primarily to drive external analog
circuitry. Examples may include the switching in or
out of gain sections or filter sections (eg., ring trip
filter) (Figure 7).

and 7 ( when both at logic high) of Register A
which in turn receives its control word input
via CSTi, when F1i is low and CA input is
either at V EE or GNDD. Power is removed
from the filters and analog sections of the chip.
The analog ouput buffer at V R will be
connected to GNDA. DSTo becomes high
impedance and the clocks to the majority of the
logic are stopped. SD outputs are unaffected
and may be updated as normal.
2)
CSTi Input. With CA at VEE and CSTi held at
continuous logic high the chip assumes the
same state as described in External Control
(1) above.
Internal Control:
1)
2)
Initial Power-up. Initial application of VDD and
VEE causes powerdown for a period of 25 clock
cycles and during this period the chip will
accept input only from C2i. The B-register is
reset to zero forcing SD0-5 to be inactive. Bits
0-5 of Register A (gain adjust bits) are forced
to zero and bits 6 and 7 of Register A become
logic high thus reinforcing the powerdown.
Loss of C2i. Powerdown is entered 10 to 40
µs after C2i has assumed a continuous logic
high (V DD). In this condition the chip will be in
the same state as in (1) above.
Note: If C2i stops at a continuous logic low
(GNDD), the digital data and status is
indeterminate.

Note 3:
The filter characteristics are totally dependent upon the accuracy of the clock frequency providing F1i is synchronized to
C2i. The A/D and D/A functions are unaffected by changes in clock frequency.
Note 4:
This gives a 75 ns period, 50 ns before and 25 ns after the 50% point of C2i rising edge, when change in F1i will give an
undetermined state to to the internally synchronized enable signal.
