1. DESCRIPTION
The S1T98B00 B and S1T98B00 D Series are 32768Hz PLL oscillators that output PLL oscillation by
*** ***
externally providing 32768Hz crystals.
There are four types of packages - WAFER (S1T98B00W 0), CHIP (S1T98B00D 0), SOP3A-16
***
***
(S1T98B00M B1), and SSOP2-16 (S1T98B0M D1) - to choose from to your specific applications.
** **
The CMOS IC for these series contains a crystal oscillator circuit. Externally attaching a crystal oscillator to
the built-in crystal oscillator circuit allows any of these series to output PLL oscillation and 32768Hz clocks
from 32768Hz oscillation source.

Locate 0.1µF ceramic capacitors (used as bypass capacitors) as close as possible to the package to place them
between VDD and VSS, VDD2 and VSS, and VBK and VSS and measure the jitter.
Instruments: Use the standard instruments provided by Seiko Epson.

9.3 Implementation Guidelines
1) VSS should be connected to the ground plane of PCB.
2) The VBK should be kept equal to VDD when PLL is running.
3) C1 to C4 are ceramic bypass capacitors. C1 and C2 must have a value of 0.1µF and C3 and C4 = 1nF. It
is important to place them as close to the + power supply pins, VDD and VBK, as possible and connect the
other ends to a ground plane on the PCB. Make the length of wiring as short as possible so that the area
of loop between each positive power supply and ground is minimized.
Applying excessive level of extraneous noise to power source or input terminal may cause latch up or
spurious phenomenon, which results in malfunction and breakdown.
4) The crystal oscillators must be placed as close to XG and XD pins as possible.
5) Avoid routing signal and/or power supply lines near the oscillator circuit (particularly crystal oscillator).
6) The insulation resistance between XG and XD pins and PCB should be as high as possible (200MΩ or
more).
7) Avoid condensation, which should cause the crystal oscillator to stop.
8) Avoid setting up any input pin potential to middle, which results in increased power consumption, reduced
noise margin, damaged elements, etc. It is recommended that the potential of any input pin be set up as
close to the VDD or VSS potential as possible.
Since any input pin has a very high impedance, avoid leaving them open to prevent malfunction caused by
potential inaccuracies or noise. It is required to use pullup or pulldown resistors on any unused input pins.
Each of the test pins (VREG, TST0 to TST3, SNX, TSEN, and VC) has a pulldown resistor. Leave them
floating.
9) Static electricity
Although an anti-static-electricity protection circuit is provided in the circuit, excessive levels of static
electricity may damage the IC. Choose conductive materials for packing and container. Use a soldering
gun and a measuring circuit free from high-voltage leak and provide grounding connection when working
with them.
