FUNCTION
RECLED
25
Record LED
: The RECLED output is LOW during a record
cycle. It can be used to drive an LED to indicate a record
cycle is in progress. In addition, RECLED pulses LOW
momentarily when an end-of-message is encountered in a
playback operation.
XCLK
26
External Clock
: The input has an internal pull-down device.
The ISD1400 is configured at the factory with an internal
sampling clock frequency that guarantees its minimum
nominal record/playback
time. For instance, an ISD1420
operating within specification will be observed to always have
a minimum of 20 seconds of recording time. The sampling
frequency is then maintained to a variation of +2.25 percent
over the commercial temperature and operating voltage
ranges, while still maintaining the minimum specified
recording duration. This will result in some devices having a
few percent more than nominal recording time.
The Internal clock has a +5 percent tolerance over the
industrial temperature and voltage range. A regulated power
supply is recommended for industrial temperature parts. If
greater precision is required, the device can be clocked
through the XCLK pin as follows:
EXTERNAL CLOCK SAMPLE RATES
Part Number
Sample Rate
Required Clock
ISD1416
8.0 kHz
1024 kHz
ISD1420
6.4 kHz
819.2 kHz
These recommended clock rates should not be varied
because the antialiasing and smoothing filters are fixed, and
aliasing problems can occur if the sample rate differs from the
one recommended. The duty cycle on the input clock is not
critical, as the clock is immediately divided by two. If the
XCLK is not used, this input must be connected to
ground.
