E1
MCLK: Master Clock
This is an independent, free running reference clock. A clock of 1.544 MHz (for T1 mode) or 2.048 MHz
(for E1 mode) is supplied to this pin as the clock reference of the device for normal operation.
When MCLK is low, all the receivers are powered down, and the output pins RCn, RDPn and RDNn are
switched to high impedance.
In transmit path, the operation mode is decided by the combination of MCLK and TCLKn (See Table-2
System Interface Configuration for details).
NOTE: Wait state generation via RDY/ACK is not available if MCLK is not provided.

LOSn: Loss of Signal Output for Channel 0~7
A high level on this pin indicates the loss of signal when there is no transition over a specified period of
time or no enough ones density in the received signal. The transition will return to low automatically when
there is enough transitions over a specified period of time with a certain ones density in the received sig-
nal. The LOS assertion and desertion criteria are described in 2.4.3 Loss of Signal (LOS) Detection.

MODE2: Control Mode Select 2(2)
The signal on this pin determines which control mode is selected to control the device:
Hardware control pins include MODE[2:0], TS[2:0], CLKE and OE.
Serial host Interface pins include CS, SCLK, SDI, SDO and INT.
Parallel host Interface pins include CS, A[4:0], D[7:0], WR/DS, RD/R/W, ALE/AS, INT and RDY/ACK. The
device supports multiple parallel host interface as follows (refer to MODE1 and MODE0 pin descriptions
below for details):
MODE1
I
43
K2
MODE1: Control Mode Select 1(2)
In parallel host mode, the parallel interface operates with separate address bus and data bus when this pin
is low, and operates with multiplexed address and data bus when this pin is high.
In serial host mode or hardware mode, this pin should be grounded.
MODE0
I
88
H12
MODE0: Control Mode Select 0(2)
In parallel host mode, the parallel host interface is configured for Motorola compatible hosts when this pin
is low, or for Intel compatible hosts when this pin is high.
In serial host mode or hardware mode, this pin should be grounded.
CS
I
(Pulled to
VDDIO/2)
87
J11
CS: Chip Select (Active Low)
In host mode, this pin is asserted low by the host to enable host interface. A high to low transition must
occur on this pin for each read/write operation and the level must not return to high until the operation is
over.
In hardware control mode, this pin should be pulled to VDDIO/2.
