PM5342

The PM5342 is designed as the TUPP+622 SONET / SDH payload extractor / aligner that implements significant functions for a SONET/SDH compliant line interface. Also PM5342 transmits SONET/SDH frames, via a bit serial interface, and formats section, line (multiplexer section), and path overhead appropriately.

Features of the PM5342 are:(1)Provides integrated clock recovery and clock synthesis to allow a direct interface to optical modules;(2)Provides a standard 5 signal P1149.1 JTAG test port for boundary scan board test purposes;(3)Provides a generic 8-bit microprocessor bus interface for configuration, control, and status monitoring;(4)Low power +5 Volt CMOS. Device has PECL and TTL compatible inputs and TTL outputs;(5)256 pin Super BGA package. Supports Industrial Temperature Range (-40°C to 85°C) operation.

The absolute maximum ratings of the PM5342 can be summarized as:(1)Ambient Temperature under Bias: -40°C to +85°C;(2)Storage Temperature: -40°C to +125°C;(3)Supply Voltage (+3.3 Volt VDD3.3): -0.3V to +4.6V;(4)Supply Voltage (+2.5 Volt VDD2.5): -0.3V to +3.5V;(5)Voltage on Any Pin: -0.3V to +6.0V;(6)Static Discharge Voltage: ±1000 V;(7)Latch-Up Current: ±100 mA;(8)DC Input Current: ±20 mA;(9)Lead Temperature: +230°C.
