ISO²-CMOS MT8960/61/62/63/64/65/66/67

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 V_EE, and in the second period CA must be

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).

On initial power-up these registers are set to the

powerdown condition for a maximum of 25 clock

cycles. During this time it is impossible to change

the data in these registers.

Chip Testing

By enabling Register B with valid data (eight-bit

control word input to CSTi when F1i=GNDD and CA=

V_CC) 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_Xinput and the output in

each case is V_Routput. (See Table 3 for details.)

FUNCTION CONTROL

Digital Loopback

Analog Loopback

Powerdown

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:

Table 2. Control States - Register A

•

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.

•

Analog output buffer at V_Rhas its input shorted

to GNDA and disconnected from the receive

filter output.

•

Analog input at V_Xis disconnected from the

transmit filter input.

•

The digital input to the PCM digital-to-analog

decoder is disconnected, forced to zero (0).

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

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.

V is not tested by this configuration.

Analog loopback is defined as follows:

•

PCM input data is latched, decoded and filtered

as normal but not output at V_R.

In both cases of loopback, DSTi is the input

and DSTo is the output.
