DESCRIPTION
The PL685 is a Dual LC core monolithic IC clock, capable of maintaining sub-1ps RMS phase jitter, while covering a wide frequency output range up to 800MHz, without the use of external components. The high performance and high frequency output is achieved using a low cost fundamental crystal of between 19MHz and 40 MHz. The PL685 is designed to address the demanding requirements of high performance applications such as Fiber Channel, serial ATA, Ethernet, SAN, SONET/SDH, etc. 88.6 mil XIN XOUT 65 mil SCLK 9 8 Die ID OE/PDB/ SDIO DNC 10 11 GND_ANA GND_DIG GND_BUF 12 13 14 (0,0) PL685 (1650,2250) 7 6 VDD_ANA 5 VDD_DIG 4 VDD_BUF 3 QB 2 VDD_BUF 1Q DIE SPECIFICATIONS Name Size Reverse side Pad dimensions Thickness Value 65 x 88.6 mil GND 80 micron x 80 micron 8 mils OUTPUT ENABLE CONTROL OE Select (Programmable) OE State 0 0 (Default) 1 Output enabled Tri-state 1 (Default) 0 1 (Default) Tri-state Output enabled BLOCK DIAGRAM OE/PDB XIN/REF XOUT Xtal Osc (Default pre-programmed output path) PD/CP LF – HF LCVCOs Pre-scalar 4/6 /2 Programmable Function M Divider (5 bit) P Divider (4 bit) /2 Q QB Micrel Inc.
