PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE 2 PM5350 S/UNI-ULTRA DATASHEET ERRATA PMC-1990107 ISSUE 4 SATURN USER NETWORK INTERFACE 2 INDUSTRIAL TEMPERATURE OPERATION The device has been re-qualified for operation in industrial temperature conditions under certain circumstances. Specifically, if the device is operated in PECL mode only (i.e. with PECLSEL selected TTL high) the device can be used in industrial temperature conditions (i.e. -40 to 85 degrees Celsius). However, if the device is used in UTP-5 applications (i.e. with PECLSEL selected TTL low) the device is only rated for commercial temperature operation (i.e. 0 to 70 degrees Celsius). If the device is used in PECL mode under industrial temperature conditions certain timing parameters will be changed. However, the device can be used in PECL mode under commercial temperatures without modifying the timing. 2.1 Page 183 Page 183 section 10 "Absolute maximums" has been changed to the following: Ambient Temperature under Bias (UTP-5) Ambient Temperature under Bias (PECL) Storage Temperature Supply Voltage Voltage on Any Pin Static Discharge Voltage Latch-Up Current DC Input Current Lead Temperature Junction Temperature 0C to +70C -40C to +85C -40C to +125C -0.5V to +6.0V -0.5V to VDD+0.5V 1000 V 100 mA 20 mA +300C +150C 2.2 Pages 197-199 Pages 197-199 Tables 6 and 7 of the issue 5 datasheet has changed to the following: PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS' INTERNAL USE 3 PM5350 S/UNI-ULTRA DATASHEET ERRATA PMC-1990107 ISSUE 4 SATURN USER NETWORK INTERFACE Table 6 - Drop Side Receive Synchronous Interface (TSEN = 0) (Figure 28) Symbol Description RFCLK Frequency RFCLK Duty Cycle tSRRDENB tHRRDENB tPRDAT tPRXP tPRCA tPRSOC RRDENB to RFCLK High Setup RFCLK High to RRDENB Hold RFCLK High to RDAT[7:0] Valid RFCLK High to RXPRTY Valid RFCLK High to RCA Valid RFCLK High to RSOC Valid 40 4 1 2* 2* 2 2 14 14 14 14 Min Max 50 60 Units MHz % ns ns ns ns ns ns * NOTE: For PECL mode (i.e. not for UTP-5, PECLSEL pin driven TTL high) under industrial temperature, -40C to 85C operation (instead of 0C to 70C operation), the following timing parameters change: tPRDAT is 1.5ns for MIN. instead of 2ns tPRXP is 1.5 ns. for MIN. instead of 2ns Note PECL operation under 0C to 70C conditions can use the original values in Table 6.

If the power ramp is too slow the S/UNI ULTRA will be unable to lock to received data. The required ramp rate is a strong function of temperature, as shown in Table 1. Table 1 Maximum RAVD2 Power-up Ramp Time vs. Temperature Tambient (C) 25 0 -40 Maximum Ramp Time Requirement (10% to 90% voltage ramp) 50ms 1ms 1ms Devices that are not powered up correctly will recover normal operation when the ambient temperature rises. Once operating normally, a device will continue to operate normally over the full rated temperature range. Recommendation Some board-level power supplies cannot provide the required voltage ramp rates for proper operation at 0C or -40C, so an external circuit is needed to gate the power to RAVD2. A recommended circuit is given below. VCC 2.7ohm Si2301DS 36 PM5350 S/UNI-ULTRA RAVD2 68uF 0.1uF RESET (active high) Resistor, capacitors are part of existing supply filtering recommendations in reference design. The RESET signal is a standard CMOS signal: 0 to 5V swing with trise and tfall <20ns. During device power-up, RESET must be held active (high) for at least 10ms to allow the capacitors to discharge. Then, when RESET is brought low, the device will begin operating normally.

Performance with Recommendation All devices will power-up correctly over the entire industrial temperature range (-40 to 80C). Performance without Recommendation Upon power-up at low temperature, some devices may not lock to reference clock (RROOLV=1 in register 08h) and to data (RDOOLV=1 in register 80h). In this condition, the reference clock output (RCLK, pin 55) may be DC or very low frequency.

A non-polarized 0.1 uF capacitor must be connected between RCAP1 and RCAP2 for UTP-5 mode. A proper capacitor CRX must be used to provide proper frequency response for the Twisted-pair baseline wander correction circuit. These inputs can be tied to RAVS3 analog ground for PECL mode operation. Please refer to the APPLICATIONS and the EXTERNAL COMPONENTS sections of this document for a detailed CRX specification.
