2:4 3.3V PCIe Clock Mux
9DML04
Description
The 9DML04 devices are 3.3V members of IDT's
Full-Featured PCIe family. The 9DML04 supports PCIe
Gen1-4 Common Clocked (CC), Separate Reference no
Spread (SRnS), and Separate Reference Independent
Spread (SRIS) architectures. The part provides a choice of
asynchronous and glitch-free switching modes, and offers a
choice of integrated output terminations providing direct
connection to 85or 100transmission lines. The
9DML04P1 can be factory programmed with a user-defined
power up default SMBus configuration.
Recommended Application
Servers, ATCA, ATE, Master/Slave applications
Output Features
4 – 1~200 MHz Low-Power HCSL (LP-HCSL) DIF pairs
9DML0441 default ZOUT = 100
9DML0451 default ZOUT = 85
9DML04P1 factory programmable defaults
Key Specifications
PCIe Gen1-2-3-4 CC compliant
PCIe Gen2-3 SRIS compliant
DIF additive cycle-to-cycle jitter <1ps
DIF output-to-output skew <50ps
Additive phase jitter is <0.1ps rms for PCIe
Additive phase jitter 160fs rms typ. @156.25M (1.5M to
10M)

Features/Benefits
Direct connection to 100(xx41) or 85(xx51)
transmission lines; saves 16 resistors compared to
standard PCIe devices
76mW typical power consumption; eliminates thermal
concerns
Spread Spectrum (SS) compatible; allows SS for EMI
reduction
Customer defined power up default can be factory
programmed into P1 device; allows exact optimization to
customer requirements:
control input polarity
control input pull up/downs
slew rate for each output
differential output amplitude
output impedance for each output
OE# pins; support DIF power management
HCSL-compatible differential inputs; can be driven by
common clock source
Selectable asynchronous or glitch-free switching; allows
the mux to be selected at power up even if both inputs are
not running, then transition to glitch-free switching mode
Space saving 24-pin 4x4mm VFQFPN; minimal board
space

Note: Resistors default to internal on 41/51 devices. P1 devices have programmable default impedances on an output-by-output basis.
