PM73123-PI

The PM73123-PI is designed as one kind of frame engine and datalink manager device that constants bit rate (CBR) data streams and each data stream (timeslot) carries an 8-bit byte of HDLC traffic, as described in the following section, and PM73123-PI is characterised by 8 KHz framing. This device may be configured to support H-MVIP and may be configured to interface with H-MVIP digital telephony buses at 2.048 Mbps.

Features of the PM73123-PI are:(1)Single-chip multi-channel HDLC controller with a 66 MHz, 32 bit Peripheral Component Interconnect (PCI) Revision 2.1 bus for configuration;(2)Supports up to 256 bi-directional HDLC channels;(3)Supports up to 32 bi-directional HDLC channels;(4)Supports three bi-directional HDLC channels;(5)Links configured for channelised T1/J1/E1 or unchannelised operation;(6)For each channel, the HDLC receiver supports programmable flag sequence detection, bit de-stuffing and frame check sequence validation..

The absolute maximum ratings of the PM73123-PI can be summarized as:(1)Case 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 non-PCI Pin: -0.3V to +6.0V;(6)Voltage on Any PCI Pin: -0.5V to VDD3.3 + 0.5V;(7)Static Discharge Voltage: ±1000 V;(8)Latch-Up Current: ±100 mA;(9)DC Input Current: ±20 mA;(10)Lead Temperature: +230°C;(11)Absolute Maximum Junction Temperature: +150°C.
