2 / 16 page Rev 1.8, August 10, 2007 Page 2 of 16 SL15100 Pin Configuration 8-Pin TSSOP Pin Description Pin Number Pin Name Pin Type Pin Description 1 VDD Power Positive power supply. 2 XOUT Output Crystal or ceramic resonator output pin. Leave this pin unconnected (floating) if external clock is used at Pin-3. 3 XIN/CLKIN Input Crystal, ceramic resonator or external clock input pin. 4 PD#/OE Input User Programmable PD# or OE control pin. Power Down (PD#-Active Low): If PD#=0(Low), the device is powered down and both SSCLK and REFOUT outputs are weakly pulled low to VSS. Output Enable (OE- Active High): If OE=1(High), the SSCLK and REFOUT outputs are enabled. PD# or OE is weakly pulled high to VDD. 5 VSS Power Power supply ground. 6 SSCLK1 or REFCLK1 Output This pin can be programmed as SSCLK1 or REFCLK1. 7 SSCLK2 or REFCLK2 Output This pin can be programmed as SSCLK2 or REFCLK2. 8 SSON#/FS Input Programmable SSON# or Frequency Select (FS) Control pin. If SSCG# function is programmed: Spread-on=0(Low) or Spread-off=1(High). If FS function is programmed: The clock frequencies can be switched between two sets of frequencies as programmed. SSON# or FS is weakly pulled low to VSS. |
