IDT82V2048L OCTAL T1/E1 SHORT HAUL ANALOG FRONT END
INDUSTRIAL TEMPERATURE RANGES

FUNCTIONAL DESCRIPTION
2.1
OVERVIEW
The IDT82V2048L is a fully integrated octal short-haul analog front
end (AFE), which contains eight transmit and receive channels for use in
either T1 or E1 applications. The raw sliced data (no retiming) is output
to the system. Transmit equalization is implemented with low-impedance
output drivers that provide shaped waveforms to the transformer, guar-
anteeing template conformance. Moreover, testing functions, such as
JTAG boundary scan is provided. The device is optimized for flexible
software control through a serial or parallel host mode interface. Hard-
ware control is also available. Figure-1 on page 1 shows one of the eight
identical channels operation.
2.2
T1/E1 MODE SELECTION
T1/E1 mode selection configures the device globally. In Hardware
control Mode, the template selection pins TS[2:0], determine whether
the operation mode is T1 or E1 (see Table-5 on page 14). In Software
Mode, the register TS determines whether the operation mode is T1 or
E1.
2.2.1
SYSTEM INTERFACE
The system interface of each channel operates in Dual Rail Mode
with data recovery, that is, with raw data slicing only and without clock
recovery.
The Dual Rail interface consist of TDPn1, TDNn, TCLKn, RDPn,
RDNn and RCn. Data transmitted from TDPn and TDNn appears on
TTIPn and TRINGn at the line interface. The interface of the AFE is
shown in Figure-4. Pin RDPn and RDNn, are raw RZ slice outputs and
internally connected to an XOR which is fed to the RCn output for
external clock recovery applications.
2.2.1.1 SYSTEM INTERFACE CONFIGURATION
For normal transmit and receive operation, the device is configured
as follows:
In host mode, MCLK can be either clocked or pulled high. If MCLK is
pulled high, TCLK1 has to be provided for proper device operation. In
addition, register e-AFE2 has to be set to ‘FFH’ to ensure proper device
operation. See Expanded Register Description on page 28 for details.
In hardware mode, MCLK has to be pulled high and TCLK1 has to be
provided for proper device operation.
Depending on the state of TCLK1 and TCLKn, the transmitter will
Transmit All Ones (TAOS), will go into power down, or will go into high
impedance.
The status of TCLK1 and TCLKn has no effect on the receive paths.
By setting MCLK low, all the receive paths are powered down.
Table-2 summarizes the different combinations between MCLK and
TCLKn.
1. The footprint ‘n’ (n = 0 - 7) indicates one of the eight channels.
2. The first letter ‘e-’ indicates expanded register.
