DATASHEET

PM5349 S/UNI-QUAD

PMC-971239	ISSUE 6	SATURN USER NETWORK INTERFACE (155-QUAD)

The RXD+/- inputs to the S/UNI-QUAD are DC coupled as shown. The device has a true PECL receiver so only termination resistors are required.

Ceramic coupling capacitors are recommended.

Notes: Vpp is minimum input swing required by the optical PMD device.

Vbb is the switching threshold of the PMD device (typically Vdd - 1.3 volts)

Vpp is Voh - Vol (typically 800 mVolts)

Vpp = (Zo/((RS1+Rs)+Z0) * Vdd

-Vdd (S/UNI-QUAD’s analog transmit power) 3.3V

-Zo (trace impedance) typically 50Ω

-Rs (TxD source impedance) typically 15-20Ω

-RS1 : ~ 158Ω

For interfacing to 5.0V ODL, R1 : 237Ω , R2 : 698Ω

Rd : 330Ω

For interfacing to 3.3V ODL, R1 : 220Ω, R2: 330Ω

Rd : 150Ω
