10 / 36 page ISD4003 SERIES Publication Release Date: March 3, 2017 - 10 - Revision 1.32 PIN NAME FUNCTION SOIC / PDIP XCLK 26 External Clock Input: The ISD4003 series is configured at the factory with an internal sampling clock frequency centered to 1 percent of specification. The frequency is then maintained to a variation of 2.25 percent over the entire commercial temperature and operating voltage ranges. The internal clock has a –6/+4 percent tolerance over the industrial temperature and voltage ranges. A regulated power supply is recommended for industrial temperature range parts. If greater precision is required, the device can be clocked through the XCLK pin as follows: Part Number Sample Rate Required Clock ISD4003-04M 8.0 kHz 1024 kHz ISD4003-05M 6.4 kHz 819.2 kHz ISD4003-06M 5.3 kHz 682.7 kHz ISD4003-08M 4.0 kHz 512 kHz These recommended clock rates should not be varied because the anti-aliasing and smoothing filters are fixed. Otherwise, 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. SCLK 28 Serial Clock: This is the input clock to the ISD4003 device. It is generated by the master device (typically microcontoller) and is used to synchronize the data transfer in and out of the device through the MOSI and MISO lines, respectively. Data is latched into the ISD4003 on the rising edge of SCLK and shifted out of the device on the falling edge of SCLK. |
