FUNCTIONAL DESCRIPTION
The DS32kHz requires four pins for operation: V
CC
, GND, V
BAT
, and 32KHZ OUT. (See Figure 3 for connection
schemes.) Power is applied through V
CC
and GND, while V
BAT
is used to maintain the 32kHz output in the absence
of power. The output is accurate to ±7.5ppm (±4 min/yr) from –40°C to +85°C and ±2ppm (±1 min/yr) from 0°C to
+40°C.
The DS32kHz is packaged in a small 36-pin SMD using ball grid array (BGA) technology
with dimensions 0.400" wide, 0.450" long, and 0.124" high. It also is available in a 14-pin DIP module.
The additional board space required is negligible in most applications and, therefore, the recommended land
pattern layout should be implemented on all new designs and future board revisions to satisfy applications requiring
better timekeeping accuracy.
