• Manufacturer Part Number: mk1493-14
• Description: Spread Spectrum Clock Generator
• Manufacturer: Integrated Device Technology

IREF
If board target trace impedance (Z) is 50Ω, then RSET = 475Ω (1%), providing IREF of 2.32 mA, output current (I
equal to 6*IREF.
Notes
1) The typical frequency is not specified since this is a spread clock.
2) Measured at 10 µs.
3) This spread range and rate result in a cycle-to-cycle jitter 0f 0.1 ps.
4) Longest period including jitter and spread minus shortest period including jitter and spread equals 301 ps.
5) longest period including jitter and spread minus shortest period including jitter and spread equals 352 ps.
6) Longest period including jitter and spread – shortest period including jitter and spread equals 403.
7) When the output is transitioning between logic 0 and logic 1 or logic 1 and logic 0, the outputs shall monotonically transition
between V
8) Calculated as 2*(T
9) Measured across R
10) Peak change in output differential voltage when driving a logic 0 and when driving a logic 1 under DC conditions.
11) Peak change in output differential voltage when driving a logic 0 and when driving a logic 1 under AC conditions.
